Who are you……???

On the #Compass TL, your followers can comment, right? ……………And who might you be (￣▽￣;)??? Of course, I know people I interact with, but when someone I don't remember commenting, someone I haven't matched with recently, shows up, I have no clue. It's tough because I can't tell if it's an inside joke, a prank, or trolling. Does everyone know who they're replying to??? How do you guys remember them???
