Tags are for organizational purposes.

Tags are not communities.

If people don’t tag their problematic content with the main fandom tags, then it not only becomes unsearchable, it also becomes unfilterable.

What if I hate undertale, and I don’t want to see any undertale posts?

If people who post problematic undertale content don’t tag it as undertale, then I can’t filter it out, and I end up with a bunch of problematic undertale content on my dashboard that I’d rather avoid.

Use the main tags.

The main tags are for everyone.

Tags are not a community.

If you really want a community tag that isn’t for problematic posts then post them as “#fandomname community” or something.

TAGS ARE INFORMATIONAL AND ORGANIZATIONAL.

TAGS ARE NOT COMMUNITY.
