Sounds like a mod / admin issue. Users can downvote and report. Mods and admins can ban. If I were a mod, I'd make a rule for it ban those two and blacklist the sites. I looked at them and they do indeed look like autogenerated slop. As a user I'm gonna start downvoting and likely reporting.

The appropriate first action is to raise awareness, kinda like this post, except without the guilt tripping.

E: It looks like stermy4u is already banned.
