Well, i assume i used to bot 4~5 years ago, i got alot of bans and learned my lesson...
I stop botting, stop playing for years. I back to L2 4 months ago like a legit player.
I play with 1 box, some times 2 or 3 boxes, i dont have any 3rd party software installed, im pretty sure i have any log from 4 years before, and all my boting toons i had got perma ban with no warns.
All my toons now are fine, no ban hammer hitting my head.
All those ppl crying because of some days ban should be thankful, some years ago, perma ban happen for the first call, never "some days".
About automated ban hammer, NCSoft just can't do it, remember, this is a BUSINESS, if they fail even with 1 acc, they are assuming a big risk to get legal problems.
Private servers are arleady illegal, so, they don't care about it.
If you get ban, it's your right to seek your rights, but remember, NCSoft probably have all proofs against you to avoid this kind of problem.
Stop botting, uninstall all your 3rd party software and see what happens...
