Just be aware that sites where files that are legally in a gray or black area are offered, especially if that content seems to be monetized in any way (eg by banner ads), tend to be untrustworthy: Someone who doesn't respect intellectual property in order to profit from running such a site could potentially also be someone who doesn't respect the integrity of your computer or personal data if they can make a profit from not respecting it. I am not commenting on the ethical issues/controversy.
There is a sad truth: If some company makes something freely available - unless it comes with a license that allows redistribution! - and ceases to do so, anything available on the internet after that time will be a bootleg copy in nature.
