Ugh, I could rant all day about Mate Centers. I mean, I don't mind the Adoption Centers, but I do get strongly annoyed when I see a Mate Center.
My reason for this is because, like someone said, you get chosen by the look of your character. Yes, I can understand why some people may not want to have a sparkle wolf or sparkle cat as a mate, but still, have some respect. Most people when they see a sparkle character instantly think they are a noob. For all you know they could be a very literate and mature, they just like that style of character.
Also, it isn't just those types of characters, but any of them. This also happens in real life. People get chosen for their looks and not their personality.
Getting away from that, another reason I don't care for Mate Centers is because a lot of the time, whoever started the Mate Center advertises every.5.Seconds. Not all the time, but usually. And they also use caps lock all the time and spams the chat. My final reason is because sometimes, people will fight over who want them to be their mate. Then that leads to arguing, blocking, and just disruption.
