There is nothing silly about what faceparty.com are doing...they must try and protect their pending trademark in order to maintain their legal right to the brand name they consider legally belonging to them...
Of course "face" is generic and so is "party" but that is not the issue really...the "faceparty" trademark application is for: "Providing on-line chat rooms for transmission of messages among computer users concerning social and entertainment subject matter" so if you have a site doing something that is similar then that is just fine but if you try and bring in a domain name or brand that is perhaps confusingly similar, like "facebuddies", then the legal weasels will pounce and with legitimate reason! The FaceParty application at the USPTO claims a first use of March 24,1999...the opposition period where you could have challenged their claim to the name has long passed and the trademark (at least in the lowly US courts) has been granted....
Your website ... FaceBuddies.com was registered in 2006...and does seem to be a site that is "Providing on-line chat rooms for transmission of messages among computer users concerning social and entertainment subject matter." so in my opinion they have every right to try and stop you and will likely win in the end. You registered a domain and started a site that is eerily similar...and I think you will end up losing in the end because of that...if your facebuddies site sold an anti-dog-biting collar called the "face buddy" then there would likely be no problem but your site seems to want to be the same sort of site with the same sort of name...ummmm...does this strike you as ok?
I'm not a lwayer and I don't play one on tv but take it from my experience...the domain name and trademark business is a long and laborious nightmare that you may not want to get into!
Two years ago we got involved with a legal fight over a domain name and we had no money to hire a lawyer and spent many long nights preparing and submitting legal briefs to defend our claim because we definately had a legitimate case...I don't think you will win in the end...that's just my opinion but I look at the facts and the dates and if I was a lawayer on faceparty side I would have no trouble pointing out the infringement nuances.
My incredible story about our domain battle that is still going on is at

In this case....your face is base! :imho:
