I've discovered that "shameless people are shameless" is surprisingly common. I stumbled across a site for a new JS book one day, and it looked exactly like the personal site of one of our frontend developers. I asked him if he started selling his site as a template, and he goes pale. About 15 minutes later we found where someone had lifted all the assets off his site, replaced his name and photo, and put it up for sale on ThemeForest. Didn't even remove all the comments he left in the code. Dude was making about $2k a month with it. He ended up having to send him a cease and desist, and the guy only gave him about $3k as a settlement.
