Well, it's good and bad at the same time. It's great to get us noticed because tbh not a lot of people really know about Iris, so in that way it would be great, but it's also kinda low to go onto somebodies server to advertise another and will likely get your account banned fairly quickly, but it's up to you guys what you do.
However, anyone going onto the other two Iris servers to advertise us is absolutely fine by me because they are both thieving copy/pasters anyway and deserve all they get lol :P
