This has never happened to me, but I've seen it happen to many people. Sometimes I just say it as a joke. Especially to a person with the char name Ash. As I like the name 'Ash.' But I'm never mean to them. I always start off with. 'OMG you stole my name! Joke Joke, but I love the name. :3' Like so, because well, I LIKE THE NAME!! So, yeah, that's what I do, never have I formally accused anyone of name stealing, because it's childish, I just, you know, play around and well, apologise, or compliment afterwards :3
Some one may just tell me, I'm still accusing, but I dun give a crap
