I have one last question.I used to play in a server.I asked the GM what type of server he uses.It was L2J and was working really great.This server had a unique protection against bots.You could log in with L2Tower but every 15 minutes a captcha (letters you must write exactly as seen in the picture) was poping out.You had 10 seconds to write it.If you write it correct you can still play,if you write it wrong you have another chance (maximum 2 chances),but if you don't write it at all you get kicked from the server and your account is blocked for 5 minutes.So I was wondering where to find something like this.Of course with a payment. PS.Sorry for my bad english.

Thanks a lot but is it valid?I mean it can protect you even from L2Tower??

I want to buy a full Bot Protection system for L2J Freya Server.Is there any way to do that?I need to block programs like L2Walker or L2Tower ,etc.Thanks.
