addendum. yes so far only on in the us, eu had no such cases, however it is possible there will be a big hit when the token arrives in the eu that is atleast what some people believe, but like with everything in this "scene" it might happen or it might not nothing is 100% and whoever claims he knows something or can say for 100% sure it is this and that either lies or has no clue what he is talking about.
I think there was even a HB Dev comment on the fact that some people got caught in the tripwire event. Which would explain most, if not all, US bans in the week following the tripwire. Not going to dig this comment out. Other than that I've only ever heard of anyone getting banned using CR+Enyo in high rated arena because of (presumably) player reports.
I don't remember any posts seeing a detection from tripwire. With that being said, yes people obviously got caught from tripwire. Thousands upon thousands of players D/c'ing and you don't expect player reports? Imagine seeing half your LFR drop out because they're bots, you can bet people would be reporting that.
Dig through the old threads on the ban discussion forum following the tripwire, should be in one of them. Can't remember which HB Dev it was either. I'm fairly certain there was a small modest comment on one of all of those threads regarding it. Might've been deleted too I suppose. Edit: Found what I think I was referring to. Did not remember it saying he was unsure, but as a core developer I'd say he's just being cautious https://www.thebuddyforum.com/honorbuddy-forum/209413-hb-32bit-wow-recent-bans-5.html#post1906485
