I have emailed the @$$holes (unique email address) & told them any attempt to run popups on my systems is unathorised access & will result in legal action with a claim for punitive damages.

I also told them that any marketing info sent to the email address, or them passing on to anyone else, would result in legal action with a claim for punitive damages.

Everyone send them a similar email & they may get a wake up call.
