Per this question What's the policy on linking to non-market apps? I think we're all agreed that linking to an app on a warez-type alternative market-place is something we don't want to do.
How about when something like this question happens:
Is appbucket a legal app store? - Totally legitimate question from someone who's seen a deal that looks too good to be true, and wants to know if the site is legitimate or not.
However he's linking to the site in question in the question. this obviously makes it easier for question answerers to find the site and investigate it, so is ok in the initial question.
In this case where the community have decided that this site definitely looks shady and appears to be distributing cracked, warez versions of apps without reimbursing the authors, do we want to give that site the exposure and benefits of a link from us? Should we go back and edit the question to remove the link and just leave the site name?
