Besides that, they all use VPN/Proxy. So far I have blocked these ranges, it helped to reduce the attacks a bit: Code: 95.156.102.* 192.169.217.* 31.13.224.* 95.78.157.* 138.118.224.* 103.250.166.* 177.131.12.* 114.6.27.* 192.169.188.* 157.119.207.* 203.145.179.* 83.143.31.* 42.51.216.* 114.55.63.* 185.67.93.* 37.113.191.* 85.192.154.* 185.124.86.* 128.199.*.* 46.101.*.* 201.184.*.* 136.243.*.* 188.235.*.* 195.9.*.* 94.153.*.* 162.144.*.* 192.169.140.* 185.40.31.* 173.249.29.* 128.199.36.* 192.163.207.* 163.53.209.* 154.72.75.* 103.21.163.* 46.101.240.* 123.249.*.* 46.214.146.* 37.59.8.* 42.51.*.* 103.240.161.* 121.12.92.* 5.135.20.* 103.216.82.*

You champ! Thanks for that!

The only thing that would have been great is if OnIncomingConnection was able to pull the player's name so that we can do the name checking in that function (since GetPlayerName does not work).

Right now I check the rate in which these bots connect and if there is an anomaly then it will block their IP for 60 seconds. It seems to work a bit, I mean they do connect but they don't stay very long. I'd say maybe 75% reduced in connections alone just by checking the rate of connecting.

Got another check to see if the ID is within range otherwise it will block them (so that my NPCs dont get kicked). Will see how this holds up... Still hasn't went over the limit, yet.

Just gonna leave this info here if by chance Kalcor sees the thread and decides one day to give the issue another tackle.

GPCI is useless by the looks as someone suggested up. Different between every bot.
