I have had the "we've had no complaints" thing - when I have complained to hotels about their broken websites.
One bunch of fools had a ridiculous splash page (remember them from 1996) with a link in it saying 'Enter site' or similar (and me thinking I already had done so) but the joke was that the link wasn't visible because of some brokenness or other (memory fades) so the only way to find out where to go was to inspect the HTML tag soup source. Despite all this I did actually want to go to that hotel having been before and it was excellent. Just not listed on Google and them probably wondering why.
A local former customer of mine thought he had been sold a website by some local scumbag, but it was actually a corner of the guy's own site with a frames-based trick to make it look like an independent site. Google refused to list this piece of garbage. When I enlightened the customer he was not best please and thought about action using either my learned friends or a large pointy stick. But the victim had 'had no complaints'. Many locals were getting ripped off all the time by sharks circling the island. Unfortunately there's no one to look out for their interests now. And they never could afford me anyway, almost all thought that winging it was always the best policy or simply had no idea of the risks they were exposing themselves to.
