It is totally relevant since not only you just mentioned both of those instances, but they also have over a million users there which CP and loli culture is pervasive on those instances and hiding the problem under the rug only makes Mastodon a far worse place, given that the majority of those instances is full of that CP content which is completely illegal in lots of countries and is hardly appealing to normal users.

Right, eventually defeating the whole point of federation with more re-centralization and co-ordinated instance-level banning and you advocating a centralized government controlled social networks being much better. What could possibly go wrong? /s
> Such violent responses that you have expressed against the names of .jp and Pawoo is plausibly an indication of those developments.
What "violent responses"? The basic facts about Mastodon may indeed hurt, but you advertising those two instances that have over a million users using it for loli and illegal CP content doesn't put Mastodon in a good light and makes it completely unsuitable as a 'direct substitute' to Twitter.
