I'm less concerned about the client side ui layout, so much as for enabling spamvertisements. So for example if a feature is added to be able to search by tag someday, then theres a potential for people to try and abuse that by labeling irrevelant things under tags in order to get attention.

I've experimented with other platforms before, and whenever a search feature gets added in any system that supports multiple tags, you start seeing posts with literally two dozen or more trending tags, and its irrevelant spam. I think the big proprietary platforms like tumblr have tools to moderate these, but I am aware that a community-led version of fighting spam has different needs and tools

Theres likely a way to incorporate downvotes into the server search algo, so it isnt surfacing junk for example. All of that is just one idea of a complete plan for helping the community to moderate spam. I'm not proposing any complete strategy here.

All I'm trying to get across: don't forget to anticipate spam, and give the platform and users tools to defeat it.
