Real names don't matter to social networks. You are you because your behavior is your behavior no matter what the attached label is, and no one bothers to change that for a “fake” account. However, real names are great at keeping the naive crowds deluded about social networks being tools for “personal” communications with “real” “friends”.

> me reporting their names for being fake

So how does it feel to be in a punitive squad? Do they at least pay you well for all the atrocities?

Why did you report them?

It's somewhat annoying when people on FB are unrecognizable due to name/profile picture changes. I don't especially like FB in general, and would consider it a positive if FB enforcing their T&C caused people to leave the platform. (Or if it forced a change in the T&C.) The people I've reported are aware of my feelings.
