I have been banned once and it was an account ban.
Others i have talked to have only got the same.
I think blackhatjoe *not 100% sure on this* may have got an ip ban for the TS1 stuff but he threatnend/blackmailed aeria i think not 100% sure as i say :P
Basicaly if your going to hack either dont care or hack smart so you dont get reported/seen
Pretty much just hack to level up then do pvp normally. Grinding is lame lol.
And even if aeria does IP Ban you. If you have a Dynamic IP which everyone in my country has given to them by their ISP on broadband here then your IP changes when you reset your ADSL modem. So see if you have a dynamic ip

if you do then just change it lol.
Even then you can just use a proxy here we pay extra for a static ip so if your ISP's there give you one for free you could just ask them to change your ip just make some lame execuse like you are worried a hacker has your ip and they are going to hack you and you would like your ip changed so that it makes you feel safer and that as a customer you would be very grateful if they could change your ip for you
If you have somone tell you they are going to report you act like you dont care. Usally people do it for attention if you just say go for it i dont really mind i just play this game when im not working for something to do they probably wont bother. Did it to a guy with screen shots of me using mob finder im just like lol go for it i make hacks for this game besides your not going to bother uploading them why waste your time when you can just play im not affecting your leveling im not continously killing you i havent hacked your account and even if i was affecting your leveling you could just ask me nicely to move to another area rather than resorting to Blackmail

*I would actually move if im annoying people whilst leveling and they ask nicely lol*
