Preventing SWF reverse engineering and pirate copying

As you might already know, I recently turned once again a could-it-be-done just-for-fun-project into a released full featured product, a single player browser role playing game, actually. I created it using Flex and thus, it's just a flash game, although an abnormal huge flash game. (And it's getting bigger time after time, with a huge addition with more than 15 new quests scheduled for next week for example.)
I also created an SWF protection tool which I wrote only for Darkness Springs development, and released it later to help other Flex developers. And now, after Darkness Springs is out for one month, I am glad I did this: Pirate copying actually is really a huge problem with flash games. It is different from the PC game market where the players copy the games. Here, other Flash developers will copy and reverse engineer your game and flash game websites will grab your swf and publish it on their sites without even thinking about asking you. As I can see from the webserver logs and simple google searches, the problem is incredibly huge, basically, nobody gives a s**it about copyright, it seems. Fortunately, until now, nobody has been able to reverse engineer and republish the fully working game as it seems, only the demo without piracy counter-measures has been illegally copied on dozens of servers [which actually is good ;)].
So I am really happy about having created irrFuscator, and should you ever create a flash game, I can recommend you to use an obfuscator like it. And BTW: I added a string encryption feature to irrfuscator last week which I think should turn out to be quite useful as well.
