copying each others report format is very common in bounty. i just copying his report format and forget to edit my twitter profile.
Yes. It is possible that you make the mistake of copying someone elses data once or twice and forget to edit it, but it is highly unlikely that you would do this with the same user. And it is even less likely that the other user copied your data. Considering how many bounty hunters there are on the forum, the chances of that happening are slim to none.
and secondly P2P trading or transaction is not illegal if i was not wrong .
Sure, token transactions between two accounts are not illegal. But it is clear that they connect your two accounts and show that this wasnt random at all. You are trying to spin it, but the truth is out.
