Great article. Left out a few types, but I've seen the ones that were included.
I've also seen:
4. The will-o-wisp: Guy contacts you, seems interesting. When you contact him back, he reads your profile more carefully and disappears like a will-o-wisp.
5. The slick: This guy acts like he's really interested in you, even to the point of taking you out, when all he really wants is to get into your pants. When he realizes it will take effort, he's gone. Cis girls probably see this one too, but I think we meet more than our fair share of guys who aren't serious about us.
