Not intended to hurt anyone? Yeah, right!
Oddly, hubby and myself had something weirdly similar (or dissimilar) happen, a good few years ago now.
We bought some adult items via a mail order on the British Mainland (no shops here, to my knowledge) and as you know they sell everything from condoms to the rest of the of the oddities etc...but anyway, one day we get a letter stating that they were being taken to court and could we pay toward their charges to get them dropped or paid off (can't recall the exact details, whether they had some outstanding bills etc)...if we couldn't, of course, then the details of our name and address may not be safe and may be made public...needless to say, we never fell for it nor paid, but dropped them like a hot brick.
Pretty sure some paid even though they weren't doing anything wrong.
