...Not really? You'll get banned after so many searches anyway. (for the rest of the hour) Just like any other program I guess, don't run it for hours and hours on end.
Highly doubt you'll be able to leave it on. Because it will auto-stop when you're banned. And won't auto-start at the end of that hour's ban. Unless you can sus out a good refresh rate so you don't get banned. But then I doubt it.
You cannot run the program and be browsing the site at the same time. So yes you should be experiencing the logout problems. It's like trying to login to the account on two different computers at the same time. Not possible. Scripts allow you to stay logged in while having a "program" (script) running in the background. But no USAB scripts exist from what I know.
There is one in downloads for gm, but I don't think it works anymore.. i tested it last night and it did a bought a 99,999 item when that wasn't the lowest price (cost me 60k lols). I've never got it to work tbh but in theory it's probably pretty doable
Do either of you know if it's possible to run more than one of the USAB at once? That way i can search for 2 different items (yes I know i will have to reduce the amount of searches for each to compensate of the wizard shop ban)
