Ban accounts with IPs from china, russia, venzuela, indonesia, india, etc = home of the scammers.
WE need to get rid of these broken english speaking scammers!!!!!.
The best solution is to just remove signatures completely. In most of the threads, no actual conversation even takes place. It's just people posting their few lines for their signature campaigns. Bitcointalk would be 100x better without signatures. Keep this place for real conversations, crypto lovers, and not 3rd world crypto scammers.
you're too too naive in this cruel cruel world. Country bans don't solve any shit and it isn't wise to ban people country wise. However signature campaigns should be removed (the menace of signature campaign is much less and controlled nowadays as compared to a couple of years earlier at the time of primedice signatures)
Also, people from first world countries don't scam? They scam much easily because of their better English. A person with a bad English still gets highlighted but an american can scam much more easily than a paki.
