Yeah, it's a bit of a conundrum. Lemmygrad is the most egregious part of it and easy to block thankfully.
But I agree with some of the other posters that lemmy.ml is still pretty bad in terms of what gets allowed and who gets modetated. Luckily, this still is not an unsolvable problem in a federated world. Of course lemmy.ml could also just be blocked, but many instances will probably be reluctant to do that, as it also hosts some of the bigger communities currently. But we can make an effort to prioritize non lemmy.ml communities over their counterpart, a different meme community over memes@lemmy.ml etc, and if consensus is strong enough and enough communities shift, lemmy.ml could theoretically find itself in a position where it will have to clean up their moderation practices or risk wider defederation.
