I tried a lot of things. At first I began making a list of bots based on behaviors, and within one weekend I had over 120 in the list. I can't report all those and keep my sanity.

So I tried reporting one bot on a daily basis. Once a day for a month, the guy was in there every day pretty much. Never got actioned.

They don't care about bots, at this point I'd freely say just bot all you want. You won't get banned. SE will just discard the tickets if anyone does bother to report you.
