The onus should be on clients to filter for their user, not on everyone hiding themselves in case someone _might_ have a problem with it. Tagging should be enough.
For example, I cannot share beautiful puzzle solves in the clear simply because they are “Spoilers!” for a puzzle (in a game with hundreds)?! I should be able to tag it as spoiler and leave it at that.
Onus being on everyone sharing instead of the user privileges anodized sensibility, in effect, and it functions as insidious censorship, IMO.
This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
