Well, you better make sure you spend ALL the time necessary to review ALL of their rules and don't forget any of them. Three strikes and you are out. This sounds like a lot and seems reasonable, but the fact of the matter is if you don't know about something as simple as do not give refunds without Mercari's consent, or about the fact they recently changed or updated what is allowed, then you get get a "warning" for each thing. You can be banned and have your account deleted just for violating DIFFERENT things by accident. So, again, make sure you read and remember ALL of their rules. Every place needs to have rules, but this is getting out of control. I could understand deleting someone's account for knowingly violating the same thing like 3 times in a row or something...but goodness.....
