Context: PugJesus often spams low quality posts across the dozen or so communities they mod, apparently downvoting low effort spam on my frontpage is trolling. The only other action in the modlog is a different ban for 74 years for “Mass downvoting innocuous content,” so it definitely seems they are just banning people that dislike their spam. Glad we’re not missing out on the reddit mod experience here.
Whether or not downvoting in bulk is “trolling” or not, or is seen as that doesn’t change that I would ban people for doing it on communities that I run. It is a descriptor that changes nothing here.
I don’t see at all why it is wrong to choose to ban a user who only interacts with your community by downvoting lots of posts.
