The thought had crossed my mind that maybe MAD is downsizing and/or withering itself on the vine.
If the owners are doing any sort of maintenance and monitoring then they must be aware of the current problems, but if that's the case then the longer it goes on, the more it points towards deliberate disengagement or neglect rather than a temporary technical glitch.
If I was them and I very much wanted to keep my customers, I think I'd put a sticky thread on each forum explaining that they're "onto the problem" and normal service will be resumed soon.
