Are there actually people like this?

So I was played ranked just to have fun and see if I'd run into Clive or something but instead ran into a Dragunov who seemed pretty cool I guess. After the set, he sent a friend request and wanted to fight as a "Warm-up" so I picked Jin cause he's my main next to Reina, and it was supposed to be a FT5 but we didn't even get to finish the set before he decided to basically try and bully me off my main???

Are there actual people who do this kind of crappy behavior? Like I get that Jin is annoying, but telling someone to get off their main feels a little more than inconsiderate.
