This is a good point and I think pretty well captures the "and what is Twitter supposed to do about it" angle.
To say "well, thus and such comedian is connected to the regime, that's why he has tweeted about me," well, what level of investigation is Twitter supposed to do that they a) disprove the allegations lobbed at OP (working for RAW provocateurs) and b) are able to support the allegation against the comedian's intent, and thus prove that the whole interaction is as the OP says it is?
Doing so goes beyond moderation, it goes beyond fact checking, it's nearly at the level of a personal background check or a trial.
What is being asked of Twitter seems totally outside the realm of what a social media company should be doing. It seems like OP wanted to do the right thing, to speak truth to power, but is now realizing that power was listening.
An account that publicly exposes your identity is not the right place to antagonize people with machine guns if you are not willing to take on personal risk, and that has nothing to do with moderation policies.
