Well, that's not exactly how bannings go, but Silkroad Online is starting to crack down on their botting problem. The game has recently changed their anti-botting rules, converting over to a three strike policy. The first instance of your account being suspected, you get a 7 day ban. The next time your account gets flagged, it's a 14 day ban. And, if your account gets flagged a third and final time for the use of illegal programs, you can kiss your account goodbye.
It's a pretty strict system, doubly so for a free-to-play game. Usually we see larger MMO developers, like Square-Enix and CCP, moving towards initiatives like these. However, it's clear that Joymax is interested in cleaning up their game, a move that many will undoubtedly enjoy.
