First time in my 6 years of playing this game that I was summoned by a GM. The GM told me it was due to harassment but the email sent afterwards said it was due to me cursing and using profanity. I've never cursed at anyone when I get frustrated and that's coming from someone who regularly plays Frontlines which is one of the most frustrating places to be in the game. It may have been one of the few times I cursed at the situation (oh shit, oh damn, fuck, etc) but I may never know because GMs don't discuss in detail what exactly your violation is. I got off with a warning but I do wish they tell what, when, where you did a violation so you can at least defend yourself when you know you're right or accept it without doubting the resolution if you are guilty.
That or someone reported me because they couldn't handle my drip glam smh
Personally I would report you just for being a Miqo'te, but that's just me.
You can also be reported on the lodestone and get put in jail, so be carefui there too.
