You're confused about this. The current twitter moderation guidelines are fairly clear. A tweet cannot target someone for what I can describe as "inherent traits". The classic example is
"I hate Muslim men" = banned (Muslim and man are inherent traits)
"I hate Muslim cab drivers" = OK (cab driver is a chosen profession)
I have a friend who was banned for saying something to the effect of "I hope white men have trouble sleeping tonight"
They have specific rules and they apply them. No one is going through millions of tweets every day and seeing if they match an ideology.
That's an interesting take. I will share just a single example that flew by earlier this week that is clear evidence of this policy not being followed, either by algorithms, or by manual followup.
Content moderation can be a challenging problem, but this is a clear failure of both algorithmic and human moderation processes, and there are an enormous number of these failures that lead to real harm in the form of radicalization and targeting of individuals and groups online and the real world.
Yet Twitter is full of hate tweets towards white people and men. And they rarely get banned. I've reported hundreds. Do you care to guess how many got banned?
Also, Muslim isn't an inherent trait. It's a religion that is taught. Even your examples are faulty.
"I hate Muslim men" = banned (Muslim and man are inherent traits)
"I hate Muslim cab drivers" = OK (cab driver is a chosen profession)
I have a friend who was banned for saying something to the effect of "I hope white men have trouble sleeping tonight"
They have specific rules and they apply them. No one is going through millions of tweets every day and seeing if they match an ideology.
