I have a twitter buttons website. If I am correct, it is better not to add adsense to this kind of sites. I am right?
The only problem with that site would be insufficient content, maybe. But if you produce your own twitter buttons then I think there is no problem. The fact that you have a trademark in your domain name could become a problem ONLY if twitter does something about it, but I don't think so, who knows..
I think you need to contact admin for this hope that they have any premium membership where you can promote your business.
