At first I didn't liked the idea, but it could work as a way to filter out US centric posts and focus more on Europe.

I think it needs some guidelines: is English the preferred language? If this is limited to Europe, is it ok to have posts related to other parts of the world?

Post and find out. As with all UGC sites, it becomes what users make it. Waiting for "the rules" will probably leave you waiting for a long time.
