Nah, this whole trend to censor anything and everything that isn’t exactly what you want to see is worse for the community.
I say leave him alone. I don’t have him blocked. I don’t ever see his content unless I actually do search to see what he’s been up to (spoiler: he was a far right nutbag all along the end). Even IF he is spamming articles, that behaviour can be modded by communities he isn’t modding for, and those he is modding for can be blocked. Hell if he pisses you off specifically you can block him yourself already! This isn’t a community needs to step in issue.
As many as it takes to get you to understand censorship is a worse means. UM can ‘evade’ all he wants but he can’t take away your unsubscribe and block buttons. Did you know they aren’t single use? Amazing!
