This has already been happening on the game, specifically in Bonfire Island as I'm sure people are aware of. I really don't have an issue with people asking for mates. It's not 'mate begging' if it's a simple advertisement in General, because that's all it is. An advertisement. If it weren't, that'd be saying that asking for a pack would be 'pack begging' and so on. I regularly see 'mate advertisements' flamed by other people by shouting 'MATE BEGGER OOOOO< SHOOT IT', and 'plz dn't m8 beg tx' Really? Grow up.
On the other hand, persistently asking someone to be their mate is considered harrassment and is against the rules, which can easily be dealt with.
Back to the 'idea', I think it's perfectly adaquete so long as people don't take it seriously. Although some do, and this is usually the younger minority of FeralHeart's members. Everyone else has mates? That must mean I have to have one, too! It's up to YOU, the FeralHeart community to guide these members and show them the ropes, don't just point the finger and go haywire as the majority tend to do. And it's all fine and dandy that there's a mate section on the forums, but a large percentage of members probably fail to acknowledge that. There've been 'adoption' centers before, and they've worked fine. The same can apply with 'mate centers' when it comes to looking for someone to roleplay with as a 'mate' so long as people act maturely about it. I don't really see an issue otherwise, it's all good so long as things stay within the rules.
Edit: And if it happens to cause trollers to 'rape'... Then well, isn't that a good thing? These people must be sussed out and kicked off the site and game for good. Everyone who has read Raz's thread should already know about that.
