Content filter for profiles

[easafe]

Add a black list or whatever to avoid slurs/sleaze/hate speech to be entered on profiles (i.e. tags, names, headlines, descriptions)

We could source some kind of "bad word list", I'm not sure if including it in the codebase would create some kind of issues with github though.

Here's some random list I found: https://www.cs.cmu.edu/~biglou/resources/bad-words.txt
Tho, it even has words that are fairly tame(or just not really bad?), so it should probably be curated or something first.

Also, does merochat have any kind of user moderation code in place? I've looked around a bit and found nothing.
If not, then since these kinds of things are always a cat and mouse game, I'd suggest having a directory under src/Server that houses various types of auto mod functions for whatever we might need it for in the future.

Once we have those functions, we can just add them to the already existing systems.
Or, a slightly more complex way to do it would be to have some kind of filtration pipeline that runs on each of these systems, so in the future we only have add/modify things on the pipeline itself.
