Sadly Danielle's site is down so I can't read the original post. I also had the pleasure of interacting with BetaPunch's Twitter account a while back: they posted several tweets advertising that they were doing user testing for our service. I thought my co-founder had signed up for them but I still felt it was unethical to post details about clients publicly and asked them to tone down the tweets. The result was that they called me a "silicon valley douche"[1] which I can't help to find entertaining even still today. Only afterwards I learned that nobody from our company had signed up for them and they were using our name just to give the impression that we were using them.
