Thought you guys might want to know. I found this site hosting CCGames. They say they will remove any if the developer requests it.

Well that doesn't look encouraging at all...while you do need a Creators' Club subscription to use these, I don't like the idea that these can be distributed freely.

Is there any way a time limit on a CCGAME could be implemented in a future version or patch?  Say, like 1-2 weeks?  That would be long enough for peer review/playtest, and would prevent any abuse.  Since you need to be connected to XBL to run them, there'd be no "fooling the clock."

This site was set up during the beta and he was hosting ccgames that were either given to him, or that people had on their public websites.... he was posting in here about it. I bet most of those ccgames are GS2.0 from the DBP competition. if they are from 3.0 beta they won't even work on the 360 today.

If he hosts games he took from the review site then report him to Microsoft and I'm 100% sure he will be in a great deal of trouble: See http://forums.xna.com/forums/p/19993/104676.aspx#104676

This website exists since some time. I think the site's goal is to let the auhor's upload his/her game. If they're doing so (what I don't know), they are doing the things right. If not, in my opinion, those guys are violating the legal rules. You can't redistribute Community Games you found in Creators Club site. So, if they got them from here, they're violating the rules. And each author knows if he/she uploaded his/her game to any other website or not. That clear. Anyway, the author's owns the copyright of game, so they're violating copyrighs if the person who uploaded the game wasn't the author (something difficult to prove). It's not enough to tell the author they'll remove the game if he/she complains. The process must be the other way round: they musn't upload the game without the author's consent.

I just wrote to the website in order to warn the author's about this forums thread and asking them to read it. Hopefully, wel'll see here a response about what they're doing exactly.
