I tested it on the ARCADIA server ...
1. account = lvl 76 AK vaced at python -> ban (maybe a GM saw me)
2. account = lvl 1-34 AK -> got lvled by a mate at python -> ban
3. account = lvl 1-29 SEG -> also got lvled -> ban
4. account = lvl 27 IM -> vaced at python -> ban
5. account = lvl 1-*** AK -> lvled "normal" with vac + skillhack at maps for my own lvl -> no ban
In all cased I got 2 Dc's and at my third login I got the message, that i am penalized from the game ...
So I guess Mastershouter is right
There is something like autoban now
You will recieve a ban if u kill monsters at maps, which lvl requirements u don't have reached.
be carefull guys
best regards
