If it’s art created/posted with the express purpose of stirring up shit, that’s explicitly against site rules. If it’s targeting specific individuals, that may be harassment and can be reported by those individuals.
It’s not entirely clear whether the art you object to falls under either of those, or is just a topic that you have strong feelings about, so I don’t want to presume, but depending on exact circumstances there may be recourse.
To be honest, that's exactly the "nuclear" option that you said you are against, and honestly I'm against limiting others, or having others banned or suspended. If someone wants to try to harass me, bad-mouth me or my work or my likeings, that's their decision to waste their time on, and my decision is that I don't want to expose myself to these kind of people. Going through all the trouble, to collect evidence about why certain arts are harrasment / meanspirited is more effort than the people creating those arts deserve. If the site doesn't give a simple option for me to browse art without the need to look at the art that mocks me or my art or my interests, I simply don't browse art on the site
