I've been semi-legit rsing for 5+ years and have never had an issue. I use adblock and an autohaggler that also clicks the pet and I've never been frozen for abing. If you're worried about the confirmation pop-up, I wouldn't use it. It really only takes one small slip up to get caught cheating. For the confirmation, I just use 'enter' which is probably almost as fast as your script seeing as you have to manually click the item.
There are ways they could tell if you are using adblock, but it's basically been proven that they don't have any of these features implemented. I'd also have to guess 95% of users browsing the web use some sort of adblock, so just having an adblock isn't really something of concern. The rest just depends on timing. If your scripts are using human-like timing variables you shouldn't run into any issues.
If you have more specific questions, I'd be happy to help Overall there's virtually no risk as long as the wait times are appropriate. There's probably so many users who rs using the same method, we've likely skewed the timing threshold between bot and human to where it's basically unidentifiable regardless.
