erm, not sure about autoclicking, but there are a few options with alot less risk.
1) find an account trainer on sythe to do it for you with a paid bot fit with anti-ban and all that jazz.
2) buy the bot yourself and talk while its going, alot more reliable and alot less detectable than a simple free autoclicker.
3) do what I did before I discovered the autoclicker, build one IRL out of a Kinect motor and some pieces, the most undetectable "bot" ever is this one, as its not a bot, it actually clicks your mouse in real life and its just so damned fun to watch, pure genius! lol
PS: im not sure about other bots but the one that I use from autofighter.org is down currently. They updated it to run better but for some reason they broke it in the process as I was at 98 mage on my pure. So when it gets fixed and you decide on a trainer, I can help you. =)
Hope I helped, if you are still set on using an autoclicker, feel free but its risky and I don't want anyone to get rolled back or worse, perma-banned so be careful.
