This question contained a link to a warez site run or developed by the OP. Not only the link pointed to illegal content, but also didn't add much value to the question, so I edited it out. Was this the right thing to do? Should any further action be taken?
According to the Terms of Service (emphasis mine):
Editing the question and removing the link was appropriate. I also checked the user's other questions quickly, just in case he had a habit of posting the link. He doesn't, but had I found anything else I'd flag one of his posts for moderation attention to let team diamond know there's something fishy going on.
The user visited the question after your edit, so he probably noticed your edit message and since he didn't rollback I'm guessing he understood that sharing the link wasn't such a smart idea (and it was pointless anyway).
