Ability to attach tags to the avatar in the avatar upload form. Same minimum tag requirements as the normal image upload. These tags aren't searchable and don't participate in the search engine, they're there only for the purpose of spoilering (which iirc is handled entirely clientside), so that avatars can respect user filters (e.g. someone hates Spike but someone else has a Spike avatar). The tags attached to the user avatar can only be edited by the user in question and staff.
Potential expansions:
Ability for anyone to edit the tags on the avatar. Note: this is questionable
Display the proper "image spoiler" UI, rather than loading anonymous/default avatar in place of the offending avatar
Either that, or just spoil it like the spoiler syntax in text, revealed on hover
Public UI to view the tags attached to the user avatar (on hover? on click?). Note: privacy?
Filterable avatars
