Do what you like, just be willing to accept the associated risks is all I'm saying. That involves any garbage you may pick up from use of the program, like is mentioned already, or the possible legal outcomes. I'm sure just about everyone who's ever been sued by the RIAA initially thought to themselves, "It'll never happen to me!"
And "Big Brother" has been here for quite some time. For example, the RIAA/MPAA basically bought themselves a little piece of legislation known as the Pro-IP Act, which just unanimously passed in the Senate. While the version passed did strip out the bits where the DoJ would be effectively made into copyright police, we're still talking about effectively taking what is a civil offense, and making the federal government the enforcer of upholding it.
There's another bill being proposed... Sounds good at first blush. It gives people the right to use some copyrighted work royalty free if they perform a documented "good faith" effort to track down the copyright holder. Sounds good at first, since the little guy who may want to use some image or song or whatever, might be able to do so now. But of course you have to figure it will be large corporations that use it the most. Someone posts an image on some photo sharing site, doesn't respond to an email within a certain amount of time, the company then claims they made a good faith effort and goes ahead and uses the image in some promotional ad campaign. No doubt they will have a team of lawyers dreaming up clever ways to exploit this law to get out of paying people what they are rightfully owed.
In any case, if you're fine with the possible consequences, do as you please.
