There are many remarkable ideas proposed in this thread, I just wanted to know if it is possible or not to introduce a ban for IP, I know that there are cases where many people use a shared IP but there are cases that I reported in this forum where some people use more than 500 accounts like in this case (for abusing airdops and bounties)
1 MAN 560+ accounts on forum, Millions of tokens abused. It will work only for 1 week. Then they will learn to use a VPN/VPS/proxy to get around the problem, it's like a war lost in advance.
You also will see a ton of "Sir I can't post..." threads by people sitting in a cybercafé with wife, brothers, cousins, paying a connection 20 hours per day and used one at a time
