Rumor has it, this is from an unconfirmed source, On March 4th 2010, JaGeX filed a lawsuit again 5 or so botting websites, and they were consequently shut down.
read some stickies.. and there not shut down yet atleast, if they are going to be. unless their still updating the bot clients while shut down which is unlikely
Jagex managed to build a good enough case i believe even though china doesnt fall under the law... so i dont know i think it will come back but it will definately still be updated in the underground cheating world but probably not released publicly for a month or two
