Is there any way to block permissions on apps? I read about being able to revoke permissions on CyanogenMod, but it seems the devs took that ability out. 

I found some app out on the market for 6$ or so, but it doesn't look like it would be worth its price. It is called Permissions Denied. Any other way to block some permissions for some apps?

Thanks.
There are at least two different solutions available for it: LBE Privacy Guard (careful when you're already running JellyBean: do not use the Playstore version then, but rather check with XDA-Developers, as the playstore version causes boot-loops with JellyBean and the dev did not even place a note for it), and PDroid Privacy Protection / PDroid Manager. The latter is more difficult to install, but often preferred: being implemented at OS level, it offers more security.
