These men are colloquially known as “reply guys.” While no reply guy is the same — each reply guy is annoying in his own way — there are a few common qualities to watch out for. In general, reply guys tend to have few followers. Their responses are overly familiar, as if they know the person they’re targeting, though they usually don’t. They also tend to reply to only women; the most prolific reply guys fill the role for dozens of women trying to tweet in peace.
I once asked one of our female anchors about the grief they get from horrible idiots on the internet – she said the ones that at least think they are being nice are far worse.
