I swear, half of the arguments on here get started cause people have previous beef that they just HAVE to bring up. While I understand that they are a longstanding anti of your group since 2003 and they have personally insulted every member of your family it's not acceptable. Y'all are actively derailing threads, starting fanwars, and creating a mess in places where users are trying to have a rational discussion. And the minute you typed your shady post, made sure it was perfect, and clicked submit, people immediately forgot about the main topic of the thread and are spending their energy yelling at you, or for you!
Just block them. Or if you really need to, create a DM where y'all hash it out so that we don't have to care. It's so easy. I'm sure there are people on here who would love to instruct you if you can't figure out how to.
Furthermore, if you hate a specific group, instead of denying it when you invade their threads for the millionth time to scream about how your group is better and all of them suck please just block all their fans. Or at least the main ones who create the threads. Please. And if you can't do that, join a guild and STAY THERE!
