That is helpful, thank you. Sorry if this is OT, but does it make sense to block "bot like" low activity followers? I don't have good language for this, but I've seen several followers that look like bot like, but mostly not trolling. Does anyone fuss with this, or am I being silly?

Not silly! To moderate I ask 1) "would anything of value be lost if I never saw this user on my feed again?" And 2) "is this user someone I wish to see interacting w/my followers and replies on my feed?" Based on that I either mute or block.
