Most mods on lemmy simply ban/delete/censor people they personally don't like; the price of destroying conversations and interesting discussions to change nothing about the "safety" of the nearly non-existent community.

Our mod team is very carefully curated, as every moderator has full equal power.
It's important to always have someone available, so I try to have new people come in as mods get tired and take a few months off.
TLDR: in order to maintain such a high quality digital space, we always need a flow of new mod applicants.
