Why do people ghost?

I had 2 separate dates with 2 guys in the last while, we had texted for a bit b4 meeting up, seem to get on... had the date & then i pretty much got ghosted after... if they aren't interested i'm ok with that but its just plain rude not to actually say they aren't interested!

Whats the point? Taken the attitude that if they can't be honest they aren't worth dating!
