Old members remember a period in the history of the Forum when the trading of accounts flourished, immediately after the hacking incident in 2015.
Wow, I don't know about these; is there any thread for them?
Unfortunately, this will not stop.
Unfortunately, this will not stop, and also unfortunately, people who buy accounts will end up receiving a red tag like I have seen on some profiles (account changed hands; don't trust these users). When this tag is placed on a bought bitcointalk account, I don't think there could be any good use of that account because trust is something that I understand the forum takes very seriously.
The forum does not prevent trading accounts because it cannot stop them.
The forum cannot stop these acts, but the DT members can make those accounts useless if they find out about any one of them.
