It's true that the names are not officially documentend on government files, but that's not the point. Nothings to stop me registerning those names as non profit organisation or company and then have every right to them, for all you know I could very well have. I havn't, but I'm just trying to make the point that I could have.
I claim the names are taken, because we do have the domain names, the forum (and site to come), all the LFS servers and the mirror, and many other projects that have nothing to do with LFS but use the Silly Project name. Also, the SPTR team name is registered in LFS world, surely that gives some claim to it. Whilst Silly Project and SPTR mind their own business as a general thing, most people have heard of it, even if it's only seeing the name in the servers list before you click on a different server, and we've been around for a while now as well.
Surely you'd forgive anybody for getting annoyed at somebody copying what they're doing. It can be said that if somebody is copying you, take it as a compliment as you're obviously doing something right from them to bother. Having said that, if the server is not up to the same level as the real ones, it can reflect very badly. I'm not spouting off how great my servers are, very far from it, again, it's just another point.
The server in question is offline now anyway, but that doesn't mean the question/matter is dead. It could happen to anybody, anytime. I'm sure you'd be annoyed if you couldn't get your server online because somebody else was using the name. I can't see why people wouldn't want their own identity, and make their own name and reputation for what they're doing. Leeching off others just makes you look an idiot, in my opinion.
Anyway, I'm going on a bit ...
