You're probably overthinking it a little bit. Unless you are intimately involved with the commercial side of copyright and trademark law, there's not really much you should be concerned with as far as I can tell from what I have read of the E.U. law.
They don't want you. They don't want some game company's website where a user might post a link to something or has a Mickey Mouse avatar. Even Disney, the most litigious company on teh Earf that jealously guards and stewards its entirely library of intellectual property doesn't want "you." The law is designed to go over content-thieves relabeling the work/articles produced by others so they can draw attention to their website for commercial advertising hits and running the gambit of fraud for a quick payback. They want to force hosts like Youtube to steward their websites to prevent someone from uploading "The Bridge on the River Kwai" in its entirety, in 12 minute segments, in order to make money off of the ads that are placed in it.
Even if someone wanted to come after you, you'd likely get a Cease and Desist letter and that would be it, since showing "damages" would be a bit problematic and pursuing anything further would cost real money.
If you are somehow making extensive use of third-party intellectual property, then you'll have to sharpen your pencil a bit. But, if not, don't worry about it. Teh Interwebz meme community has gone overboard ranting about this. Sure, I think that's fine and we need some people out there fighting for creative freedom and all that, but only up to the point where they start getting irrational about it.
IF the E.U. does, in fact, go overboard with this thing and starts to look at casual artistic expression artistically using third-party intellectual property that can be said to bring additional meaning and content to what has been created by the user, then my opinion would change and likely the opinion of many in the E.U.
