Here's some quotes, that's all I can give you for now as the forum does not like members posting certain information, such as the cracking groups' names, and thus linking directly might cause a problem.
From a Mirror's Edge crackfix NFO:
The initial releases of the first Mirror's Edge crack were plagued as was, as stated below, some non-pirating users.
From a gaming blog that covers Mirror's Edge issues:
From a Mass Effect crackfix NFO:
Most, if not all, of the issues described above were SecuROM triggers and most have affected non-cracked games - although, seeing as the majority are easy to fix, many people just think that it's a "normal" bug. Now this has led to some issues, as described by another poster, when members of the BioWare forums think they have found a pirate in their midst but really, in fact, only have an innocent who was rather unlucky - with the ironic part being that the often were posting in a part of the board that only registered members could access, in other words they had already proved that they had a legal, legitimate copy.
From another Mass Effect crackfix NFO:
As above, this was a re-release due to triggers that were included. In fact, this is the very error that my Steam version had until I uninstalled it an reinstalled it (if you require confirmation that I do in fact own both a DVD and Steam version Gorth has seen evidence of this and can back this up).
