The implications of this are honestly kind of scary, because we've seen in the past as well that GMs don't care so much about the harm being inflicted as they do about the fact that someone could have been offended. In one example that I read about a couple of years ago, two friends queued leveling roulette together. A tank and a healer. They had been friends for a while, and liked to joke with each other in the chat. At one point, the tank died and jokingly blamed the healer, saying some stereotypical noob stuff like "grrr stupid healer, u let me die >

" and the healer, who, again, was friends with the tank and was not offended by this at all, just sorta laughed and went like "fku lmao" and they kept going and eventually cleared. Now, neither of these 2 involved in the interaction were offended by what the other was saying. But a DPS in the group did not know the tank and healer were friends, so he filed a report against (iirc) the tank for being mean to the healer. The tank was then disciplined over his rudeness and given a strike on his account. When the GM refused to explain what the ban was about, the tank took a wild guess and told the GM in the gaol like, "hey if it's about what I said to a healer, that was banter with a friend of mine, he knows I didn't mean that stuff" and the GM basically said that it didn't matter that they were friends, it didn't matter that nobody was actually harmed; all that mattered was that somebody else in the group who wasn't even involved in the conversation felt bothered enough to send in the report. I wish I could find the damn thread; it's been years.
Going off of that precedent and this one though, the door's basically open for me to report any name I want, for any stupid reason, and it's basically a cointoss on whether or not a GM decides my feelings warrant you changing a name that you've had for years. All the people in here talking about reporting the OP have names similar to real people I can google. I am free to report that because their real life name references "break my immersion and I'm also offended on behalf of the people they're referencing, who never asked to be used in such a way." You might think I'm being ridiculous to say something like that. You might even say that I'm misinterpreting your name. But none of that matters if we examine the precedent already set in this instance, and in other instances. All that matters is I'm upset, I'm blaming you for it, and now we'll see if a GM agrees or not. They might say it doesn't even matter that your name's harmless; since it offends me, that's enough. Now, I wouldn't do that because I'm not a rat snitch, but the precedent is there now. Congratulations. This is your game.
Just one more reason to never interact with any of the brittle people playing it.
