IL=interlude, I play on a server that probably has the same protection.
how do you know they use this protection?

If it is this the one they use, maybe try overwriting engine.dll in Lineage2\system\ whith one from a clean IL system (the one from the original L2 installation in your computer). Maybe that wont change anything, but probably they only give IP ban, so you can lift it just by changing IP.
Quote form postpasific (reply to the protection method):
"Well... that's so old method... that any kid that search in a cheaters forum longer than 10 minutes gets like 4 differents ways to retrieve the new authd key.... and all you need to do is patch any other engine.dll or the old one... also you can deatach the import from the dll...or... even you can replace the dll by another one with no code at all, you need something better than that."
What about OOG walker? Do you get banned as well?
Plz tell me if you got any results.
