The infuriating issue I'm dealing with lately is the crossover between IRL and internet friends. They refuse to stop naming when typing or speaking. I don't care that they know who I am, but there's a reason that I want my nickname being used when we're in a discord server and random fucking people join in. It's even worse on forums. You go to one meetup and suddenly someone wants to make a post saying, "it was great to meet X, Y, Z, AA, AB, AC, AD, AE, AF...." using the names of the people instead of their aliases, or worse using both. And of course they took a picture.
I blame facebook. It introduced and reinforced the concept of name=person=online to everyone.
