Hi Crypto McPoopypants (interesting name),

It's a number of things coming together, which result in the answer of this question:

- Sellers put credentials in the profile
- Rating system with reviews for prior research
- At the end of the conversation there is a popup for the seller which asks them whether they accept the payment or decline it; if the seller couldn't help / provide right answer, they can give the money back (if they don't, they could suffer a negative review and lose a lot of business).

Putting these 3 things together, we actually have a stronger basis for the correct answer than we would have with any random answer online, or even offline, as you can now check credentials and the sellers are concerned about their ratings. Normally offline, such implications aren't there.
