When people outright state "If you watch me I'll watch you"
This is when you watch someone because you genuinely like their stuff and they just watch you back for seemingly no reason.
Like, I get that people who know each other might want to do that (since FA lacks a friend system)
Of course, could just be that they also like -your- stuff too and they only found it after you watched them.
Always had a hard time with that one tho as I don't really produce any content myself and people should go watch the original artists instead.
Unless minimalistic plushies count, of course.
