what are the chances?

Well if you do not have a knowledge of scripting use a simple mouse recorder. Go to google or yahoo and you can easily find one ( i would not use one from any rs cheating site as most have trojans/keyloggers). And as many have said high alch in a place where you can not get reported/ randoms such as your own house (even get a few freinds to come alch with you and type some random "exp left??"). Using an mouse recorder is pretty risky however if you recrod yourself for an hour or so you should be right and only alch for 2-3 hours max. You should have no problems, instead of using 1 item use 2-3 items to alch, mix it up so it seems your human.

Hope this has helped you, and gl not getting banned

 

Jethrox's Autoalcher is great, alch in your house you wont get banned.

 

is there any clickers or recorders out there with random intervals? If not, I can make some...

 

Agree whit this ! Use @ own risk

 

I think the best thing to use is mouse recorders =\
