There's a number of behaviors you can pick out that you can 100% tell they're bots. Almost all of them are clearly running the same application(I obviously won't link the site here) and it's very, VERY easy to tell botted characters once you pick up the ways to distinguish them. Problem is, I can give these quirks to SE and report the same bots as much as I want, nothing ever happens. It's a waste of time. I've given up at this point and just pretty much accepted that nothing will ever be done about it. People blatantly do it on their main active service accounts with top end raiding gear/titles because there's zero risk.
