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.
You’re completely missing the point. Downvoting bad content is entirely desirable, but what constitutes bad content varies by community and instance. For example, I think most of the stuff in memes communities is pretty shit content. So I don’t subscribe to any. I don’t go to All and think “well this isn’t to my tastes, better downvote it all!”
If someone is actually spamming, not just turboposting, then report it and block it. If they’re just posting a lot, maybe point it to them, report it if it’s against the rules, and block them so you don’t see their posts. Posting a lot of stuff to relevant communities is very rarely harmful behavior.
