...now they're saying FH is copyright infringement.
Thats cause you guys havent been nice to them and played in "their court."
If you dont kiss their asses and tell them what they want to hear precisely, they wont respect your contribution, because it doesn't fit their definition of "legitimate." Then, they have no reason to give the entry much though, and might come to a dumb conclusion like that. As Lobo has said, they're Nazis. Luckily, they're idiotic Nazis who dont have power outside of they're Nazi website, so even if FH was copyright infringement they couldnt do jack shit.
Just leave it for now. Focus instead on getting FH2 into your local papers or a magazine or something.
Maybe one of the devs could host a local event and get it into their local newspaper, which would go a long way to shutting up the Wiki staff. It would also be quite fun, since some of us could buy them the beers they deserve.
