U no dat in sum groops, even dat spilling & gd grammer not importent.
I'd go as far as to say that for some communities, deliberate disruption in their language patterns are used as ingroup/outgroup markers. And, they evolve so quickly as to make it difficult for actors who are not regularly participants in the group to keep up. An example of this is the meme communities. Memes because dead memes / stale memes faster than they can be written into an internet marketer's guidebook.
It'd be great to have the grammar, spelling and appropriate tag AI-Assistants but the AIs should not be allowed to make the final decisions. It'd be awesome to see "Are you sure you want to use the CN tag? You don't appear to have Chinese content and so are likely to be seen as a spammer by the community that uses that tag. You might even get downvoted." that'd be awesome but a human should be allowed to say "Yes, just do it".
