Try even MERKAVA. We got over 2 and half years without any player banned. For more info look in my signatureQuote:
I tried the trials of ibot and openstealth. As far as I know, the safety of both programs depends on the way you use them. Kbot and Kopenstealth however, depend on Ivan's ability to crack ibot and openstealth. Although many would disagree, I think ibot and openstealth are safer than kbot and kopenstealth. I have read comments on bestbots.ro about crappy service and ban, so I am not sure what to believe. I have yet to find a complaint of ban on pbdo bot or ibot/openstealth.
