Check this crap out. I just went to powertabs.net and they had this message on there.
They linked it to this article.

Read that crap. What a load of bullshit man. Apparently, guitar tablatures online are illegal. Gay people want you to go and buy the official tab books. That's wonderful because I bet a good 70% of the stuff I listen to don't have any goddamn tab books. So people who waste their personal time to try to tab a song out for the good of the guitarist community are criminals. LOL! Learning a song according to a person's interpretation of it is a crime I guess. Now we don't only have to worry about having music content on our computers but also tabs. OH NOEZ! I HAVE POWERTAB I GO TO JAIL OMGZ PLZNO!
If you're gonna arrest people because they publish tablatures online, arrest the nubs on mysongbook.com seriously man half of those guitar pro tabs are incorrect...
