Find: no.
Report: You'd better believe it.
DVC exists in the odd overlap of Customers and Owners; IMHO, to be aware of a problem and not report it is, as my dear father used to put it, "Cutting off our nose to spite our face." I mean, if someone has the time to keep a running tally of the length of time various items remain in hallways, they have more than enough time to phone the front desk.
Well, I've heard many DIS DVCers express expectations from Disney that I felt were unrealistic, but now this: they'd better be PERFECT!

I can't think of any business anywhere that is perfect; they strive for perfection (or at least continuous improvement), but I certainly don't expect perfection from any business (or any person). Every place that I've worked, from restaurants as a teen to multi-million dollar software shops have had policies in place to address customer dissatisfaction issues - which would seem to suggest that such issues will occaisionally arise.
I'm not sure if anyone "accepts" them (I haven't yet seen a "There's blood on the sheets but that's OK" thread). Here's MHO: Disney is operating under the same business demands that all for-profit companies face, so if they - like every other company - have decided that there's a certain level of "issues" that the guest will discover, I can understand that. (Ever see the government regs on the allowable amount of insect parts per pound of flour?). I also think that it is reasonable to expect that every DVC owner, when they notice a problem, takes the few minutes to report it; preferable ASAP, but at the very least upon checkout. On a more practical level, I'd rather not see a significant MF increase to pay for more/better housekeepers or the Room Inspectors to QA 200 inspection points for each room after HK is done.
This is, so far, a blissfully academic issue for me: of the 20 nights I've spent at DVC (19 SSR, 1 VWL) we haven't experienced anything more than a burned out lightbulb (which I reported and was fixed within the hour).
Be well!
