It may not do much depending on the mods/admins, but it never hurts to report and downvote comments or posts like that.

Emphasis on reporting there, as I think sometimes that stuff lingers around because people have made a habit of only downvoting and blocking those doing that regularly. I realize in your examples it’s more likely bias or bigotry respectively, but still.

Report first, then downvote and block. Doing only the latter only makes your experience a little better, the former may help the community.

For those that may only vote and otherwise lurk, there’s a decent amount.

The inability to create multi-communities/reddits (or feeds as Piefed calls them), the absence of post-folding/deduplication for when someone posts the same article to multiple communities (sometimes similar, sometimes distinct), the absence of keyword filtering to automatically filter out stuff from local/all feeds one’s uninterested in, and these are just a few from the top of my head for those that mostly lurk.

In other words, vibe coders are today’s technologically accelerated script kiddie.

That’s arguably worse as the produced scripts may largely work and come with even less demand for understanding than a script kid’s cobbling together of code may have demanded.
