Sure, you could say that. I think it’s perfectly reasonable to communities that are potential targets of heavy downvoting to respond to it, no?
Their response is to ban people who disagree instead of maybe considering that AI slop communities are terrible and nobody wants them. You know, like how a MAGA community being down voted should maybe consider the crap they are posting isn't wanted. Yes, I am saying that AI slop communities are a comparable detriment to the fediverse in the same way as having a hate group community. Not an equivalent, but also bad and the large number of down votes should be a sign they are not wanted.
Pretty sure dbzer0 has multiple AI communities, no? So it’s more than just 1 person. Dbzer0 is the pro-AI (relatively speaking) instance here.
There is a difference between spamming a bunch of overly specific AI slop communities and a few general purpose AI topic communities. There are some dedicated AI communities that are successful, especially ones based on local models. Those are fine and I don't down vote those, just ignore them.
For example, there are a number of very specific AI communities like AI witches and AI mushrooms and AI cats with orange hair or some other overly specific topic and blocking a bunch of those is way more tedious than a couple communities. The low quality and volume of it is just spam nobody wants, and we should absolutely down vote spam.
