Buying on Classified Sites

If you've ever tried to buy anything on Craigslist, chances are you felt a little (or a lot) anxious about it. Should I give the seller my cell number? Is it safe to meet with him/her? Should I trust the seller? What will I do if I get a lemon? – these were probably some of the questions that ran through your mind.

We've experienced these frustrations first hand, and we've built Credo360 specifically to address this use case. You can watch step-by-step video of how you can use Credo360 when buying things on Craigslist (or any other classifieds site), but here are a few quick tips:

  • When replying to a post, don't do it from your personal e-mail, and always ask the buyer if they have a Credo ID. If they do, great! If not, ask them to set one up – this way, you'll be able to tell if they are a real person

  • Use Credo Messenger (instead of email or SMS) to communicate with the seller. This way, you'll keep your personal info private and will build up interaction history with the seller

  • Once you go through a transaction, confirm the transaction on Credo Messenger. This will do two things: (1) keep a record of the transaction, and (2) will give you the ability to review the seller

Selling on Classified Sites

Selling on classified sites can be both frustrating and dangerous. Frustrating, because every response you get could potentially be a scam, and you need to learn how to quickly figure out whether a person replying to your post is legit. Dangerous, for the same reasons – but also because you are putting your information out into the world with little control over who will use it or how.

We understand these pain points very well, and Credo360 is a perfect solution to try to make the process of selling on classified sites a bit easier. We have another step-by-step video to take you through the entire process, but here are a few quick tips:

  • Include a link to your Credo ID in the postings. This will show potential buyers that you are legit without giving away any of your private info

  • Never include your personal email or phone number in classified postings – if this info falls into wrong hands, you can be in a lot of trouble. Ideally, communicate with potential buyers through Credo Messenger

  • Ask all potential buyers to share their Credo IDs with you to make sure they are legit. If they don’t have one, ask them to sing up for Credo (especially if you are selling a big-ticket item such as a used car)

  • Once you complete a transaction, confirm the transaction on Credo and ask the buyer to write a review for you. This will improve your reputation and help you sell and buy items in the future

Renting Houses or Apartments

Finding a place to live, or finding someone to rent your apartment to has many of the same problems as buying or selling on classifieds sites. Arguably, the whole interaction is much more frustrating and risky (for both parties involved).

If you are looking for a place to rent, you don't want to fall victim to one of rental scams that abound on Craigslist and other classified sites. Moreover, once you move in, you want to make sure the landlord treats you fairly (e.g. will not try to keep your security deposit for no good reason).

If you are a landlord, you also want to make sure that the person you are letting live in your home is legit. Sure, once you find someone you like you can run a credit check – but that costs money and can be a hassle. So, you won't be able to do it for all potential applicants. You can also try to collect references and run through them – but this, again, is time-consuming and many landlords actually never follow up on the references they collect.

With Credo360, the whole process can be made much simpler. Just like for other use cases, we have a short video tutorial to demonstrate this, but here are the key points:

  • Whether you are a landlord or a tenant, ask the other person for their Credo ID. If they don't have one, ask them to create it. At the very least, this will let you know that you are dealing with a real person

  • If the other person has any reviews on Credo360, ask them to share these reviews with you. Viewing reviews left by previous landlords and/or tenants of the person would be especially valuable

  • Once you sign the lease, confirm the transaction on Credo Messenger and include the lease agreement as the attachment. This will keep a convenient record of the transaction, and will also let you review the other person

  • Once the lease ends, rate and write up a short review about your landlord/tenant. This will help others know if the person is trustworthy


Reddit is all about freedom of expression and speech. You can say anything and everything you like without fear of retribution or possibility of being "doxed." This is because most Reddit accounts are anonymous. Want to get off your chest how you've messed up by trying to recharge a cellphone in a microwave? – create a vanity account (takes about 10 seconds) and head to /r/tifu subreddit.

In many situations, this anonymity is great and liberating, however, there are a number of serious or even professional subreddits that focus on establishing true "credo" where user's identity and reputation matter. For example, on subreddits where users barter goods, such as /r/beertrade, new users could face serious stigma, as it's very hard for them to gain trust without some way of proving that they're not out to scam the community.

Fortunately, with Credo360 you can have the best of both worlds – you can prove to the community that you are a real and credible person without giving up your anonymity. Just link your Reddit user name to your Credo account (a short tutorial below shows exactly how to do this), and you’ll get a URL which will look something like this: You can then share this URL with other redditors to show them your verified Credo ID. But don't worry, people who look up your Credo ID directly (not through the above URL), won’t be able to see your reddit user name – keeping your anonymity intact


    Just as with Reddit, creating a Twitter account takes mere seconds, and just as with Reddit, this simplicity can be abused to create fake accounts. Even number of followers cannot be used to confirm the legitimacy of the account – there are techniques that people can use to inflate their number of followers.

    Twitter does provide some tools to make the account feel more legit. For example, you can verify your account with Twitter. But for this to work, you have to be a person of public interest for one, and you should also have your own website.

    With Credo360, there is a very simple way to add legitimacy to your Twitter account. All you need to do is connect your Twitter account to your Credo account. Once you do this, you’ll get a special URL which will look something like this: Anyone who follows this URL will be able to see your Credo ID with all the verifications you've connected to it. You can also add your Credo ID link as a website in your Twitter profile – this way, anyone who visits your Twitter profile will be able to look you up on Credo360.

    Below is a short tutorial video that we’ve put together to demonstrate how this process works.
