Yes it has. Unfortunately I can't really say much about the parties involved or what happened (I wasn't the bad guy though, promise), but it absolutely has, and if I've seen it, then either I'm a unique little snowflake (yay!), or it's happened a LOT more.
I assume that this is pretty common situation in some (even non-criminal) circles, I'm thinking of various small web hosts, content-free portal pages, direct internet resellers of something etc. Few times some of these people actually went to us seeking help with something almost clearly unethical and possibly illegal. This is in Czech republic, but from various stories on internet I extrapolate that this is probably global phenomena, maybe even more pronounced in other countries.
