Why do people on here not want id authentication before they're allowed to post?

This is to not give any ideas that I'm one of those frauds whole stole people's pictures. It's just I feel we need more authenticity and that trolls need to know they're talking to a real person and stop trying to disprove them. That way viewers and posters can get a feel on who's more honest than who isn't. You regulars already know how trolls don't like me by the way they quickly respond in their questions/profiles.
