I have. I suspect though that it was because of this one day a weird mod was banning people en masse for downvoting their accusatory post where they listed a bunch of users they claimed are Zionists. With no evidence at all. Everyone who downvoted it got banned from their community immediately. Then I noticed the weird bot behavior a day or two later. I saw another user complaining about the same bots doing this to them also. If it’s that mod, it’s a very strange and spiteful thing to do but it wouldn’t surprise me. People are strange.
