I've been on this site a whole lot longer than you have, and I've only run into toxic users a handful of times. I simply don't see them, because I don't follow them. I can passively filter out low quality users by following a carefully selected group of other discerning users. In an extreme case, I can actively filter out negative users, although I have yet to need these tools.
So those of us who have been here a while don't use #feminism. We use #grrlski. This has two obvious problems: 1) Neither thenewgreen or I can remember if it's two rs or 3. 2) It's a long damn way from obvious. I've harped at length about the fact that our tag nomenclature is entirely folklore-dependent... but the fact remains, it's a higher-quality tag.
Or that rule is not known, or feminism is now used as a pejorative tag against users you don't like to invite trolling. The community tagged this one feminism, not me, for example.
Edit: Looks like you don't see community tags until you actually go to the post. Intentional?
