Oh how I've witnessed a conversation like this many times. However, when it comes to Mate Centers, I actually don't mind them. They've done nothing generally wrong to me so I found no general reason to bestow hatred to all of them. They're human beings behind that computer screen too. Now don't get me wrong for I'd prefer if individuals actually went out and found their soul mates through roleplay and an actual bondage. Though that's not my decision to make for it is their character(s), not mine. Yes, they do cause major lag and can be annoying, though one must take in mind that it might be someone young playing the character, viewing the game more like a socializing game and not yet knowing how to roleplay nor what it even is. I've also witnessed how most people create Mate Centers out of sheer boredom. Let's admit it, we do weird/bizarre things when we're bored too. I know I do.
Besides the point, one thing I mainly view as a problem with Mate Centers is sometimes they and/or the individuals can get a bit out of hand and start speaking or acting vulgar. But that doesn't happen very much in my personal experience.
Simply put, Mate Centers are in a neutral zone with me. I don't mind them as long as they don't disrupt me and/or the community.
