Guys this problem its very annoying, i recently post this treat and it was closed by sios because the problem was solved... but again the hacker return.

I know the hacker use a dinamic ip and thats way is dificult to get gim out permently, there are some things i recomend:

1. Less VoteBan requiered votes (not specifically for this issue, but i know many people want this to ban some assholes who connect when no admin is in the server, and convince the 90% of the user to voteban is hard)

2. The hacker always get connect on hours when rarely admins are on (10pm to 12pm on GMT-4:30), so check the conection log searching for the hacker nick name and ip, the ISP always get IP Class A and they use the last 3 digit for geografical zones, compare if the are many user using that range of ip, and if not, BAN all that range. only for a while.

if there is no scripter available i can help.
