From the stance of the admins: It's none of our business.
In general, we're not responsible for policing everybody else's legal agreements that we are not party to in the first place.
That said, here's the relevant clause from our Terms of Service:
Subscriber represents, warrants and agrees that it will not contribute any Subscriber Content that (a) infringes, violates or otherwise interferes with any copyright or trademark of another party, (b) reveals any trade secret, unless Subscriber owns the trade secret or has the owner’s permission to post it, (c) infringes any intellectual property right of another or the privacy or publicity rights of another, (d) is libelous, defamatory, abusive, threatening, harassing, hateful, offensive or otherwise violates any law or right of any third party, (e) contains a virus, trojan horse, worm, time bomb or other computer programming routine or engine that is intended to damage, detrimentally interfere with, surreptitiously intercept or expropriate any system, data or information, or (f) remains posted after Subscriber has been notified that such Subscriber Content violates any of sections (a) to (e) of this sentence.
Matthew Read already included a link to our current guidance on handling copyright issues.
For questions like the one that spawned this meta discussion, it's entirely appropriate for the community to determine its own policy. In cases where that runs afoul of legalities, interested parties should contact us and if needed, we'll pass on an amended policy down to you.
It looks like software piracy has already been deemed off-topic:
Please note, however, that site policies prohibit questions of the following types:
- Piracy, and support with pirated games.
What you guys need to discuss and agree upon is whether unlocking DLC that's already on disc via "cheats" falls under that policy or whether there's another policy you want to come up with to cover these cases. There is no legal agreement here that we're obligated to enforce on sight.
