"On the Internet, nobody knows you're a dog."
You DON'T know the identity of the *person* you're dealing with anyway. You only know the identity that you're dealing with.
This is all expression, to some level artistic. I don't want anybody trolling, the same way I don't want anybody making bad music, but when you empower people to express themselves, well ::shrug::
If a person wants two identities, one friendly and the other trolling, that's their expression and their choice.
Hope it works out for them.
Like I said, someone with a professional identity and a hobby identity seems pretty reasonable, right? Makes sense?
Well, once you empower users like that some are going to do things you or I might not approve of. That's how a user-centric platform goes.
