Gee.. there's fakes on the internet? Who'd had ever thought it ?
Bots are "meachanical" and I can't see how or why anyone would want to attempt their use for that type of discussion.
The fact is, people on the net are anonymous. It's always been part of the attraction of the internet.
Some people may post looking for companions, and then change their minds. Others may feel warned to drawback by some of the reactions they get, or the feel they get for the posters personality, and choose to quietly withdraw rather than have any sort of confrontation.
