First and foremost, I would delete the ad, too. That's just rude when people come and pimp their crap in other people's communities. I flippin' hate that.

I think that you should stick to your policy of not allowing ships that have a specific community for them for the time being. You started the community to give a little love to all of the Raimundo/? pairings that didn't have an established niche. Once that ship gets a niche, it shouldn't continue to appear in your community. At least that is the way that I am understanding the situation. As for promoting those niches, I'd say to add them as affiliates as they are created.

Now, there could come a time when all of the Raimundo/? pairings have a community. I would think that would be the time to allow all of the Raimundo pairings back in. Does that make sense?
