I'd imagine having no Twitter would be preferable to actually having a Twitter account!
To some people it's so valuable to use as a means of participating in their community of choice that they're willing to keep using it despite severe harrasment.
Not being a woman gives you a big advantage against harrasment. But it can come from all sorts of weird places. My wife is a big Eurovision tweeter and encountered people who search for "Macedonia" to tweet Greek nationalist abuse at.
