AHK script alching ban rate speculation?

Hi, long time degenerate, first time poster. Apologies if this is a common topic or in the wrong forum

I used to bot heavily back in the day but now I train by hand. However, I just want to use an AHK script to get from 69-75 magic (approx 8k alches) on a legit client. Does anyone know what the chances of eating a ban for doing this are? I've heard conflicting things. I'd like to hear from people who've been banned doing it and people who haven't been banned doing it, plus any specific tips you may be able to offer.

Thanks for reading and enjoy the rest of your day
