Online anonymity unfortunately provides a platform for weirdos to also create fake profiles for their own sick amusement whatever that may be - pretending to be someone else, steal money, manipulate and bully others and the list goes on. I suppose one way to make sure profiles are held by genuine people would be to have the verified tick similar to what appears on celebrities accounts. It would be a hell of a big job to implement but something does need to be done because online trolls and catfish alike are using online anonymity more and more these days to deceive and bully people.
