Since early last year I have been dumping some PC games for Redump every now and then. Only officially published licensed copies are accepted, so no bootlegs and obvious pirate copies or anything like that. Despite that, so far at least three licensed copies of games by different publishers that I've dumped or verified have been sold pre-cracked, which I find both funny and incredibly fascinating, as in some of those cases publishers here (in a country that shall not be named) had to have the source codes for localization purposes.
Colin McRae Rally 2.0, Redump entry #18236, pre-cracked by Razor 1911 (has 1911 in the .exe), published by Buka Entertainment around 2002 
The Movies, Redump entry #106660, allegedly pre-cracked by DEViANCE, published by 1C around 2006 .png)
The Temple of Elemental Evil, Redump entry #93629 (haven't submitted verification yet), pre-cracked by FAiRLiGHT, published by Akella around 2008 (oof) 
Oh my God, it even has a watermark...
