I have a hard time believing this was / is the real version used. It doesn't seem broad enough. More likely it was a kind of smoketest that made sure that a more automated keyword checker was working. It does remind me of the XKEYSCORE (Snowden leaks) that used keywords to bubble up potential threats from emails etc https://www.businessinsider.com/nsa-prism-keywords-for-domes... .

It also mostly checks for English naughty words and not much else. People can have fun in lots of other languages, so it would seem this is a small sample.

If you liked this chaos, you'd love my 15+ years of cobbled-together efforts at limiting forum spam and the like. I suddenly don't feel quite so alone in the myriad efforts needed to tackle this sort of thing.

looks like it is limited to English only. There is whole world of non-English offense out there. Like using English characters to make national offensive words as well as using national characters to make English offensive words.

English only

Should optimize checks with a de-obfuscation function (attempt to expand non-AZ back to AZ, even if that then shoots permutations at banned word-runs).

It should probably also look more like a spam scoring system, where really obvious stuff is hard-trashed but borderline things are flagged for review / discussion.

I am also very disturbed that, as with most censorship, 'obviously bad' things such as terrorism/etc are co-mingled with 'is adult' as a negative check.

It seems reasonable for Twitch to have validated 'safe for minors' areas where names are filtered. Generic areas, where things are in the gray area and unchecked. Adult Only areas, where swears, profanity, maybe even some of the hateful things are allowed. Informed consumer choice.

It's an endless arms race. I spend a lot of time studying unsavory people and a great deal of effort goes into the development of new dogwhistles that are designed to either provoke or connect with peers while maintaining deniability.

Whoever leaked this is going to get buttbuttinated for sure.

I have a hard time believing this silly mess is an actual component of anything.
