Hi, thanks for writing in. Yes this is a legitimate concern, however there are a number of protections to help against this. The first point is that it’s 3 rounds, and if the buyer disputes all 3, then it spits the money among the 3 sellers. So the bigger risk is that your number uniquely doesn’t work, but the other sellers’ numbers do.
The second point is that it doesn’t count towards that service for your number. For example if it’s a Google account, then your number is still “unsold” or available for a future Google account sale. So you don’t lose that much.
A final point is that once the system has been going on longer, we can then adopt a trust score system. Where after a certain point, the Exchange can feel comfortable siding with the seller immediately in a dispute.
