They just did it to me, and were very evasive about it on the phone, regarding it as normal practice. Part of the problem is that they don't confirm that a person who signs up on their site is actually the owner of the email address involved.
That's a standard ethical practice on the 'net, we do it consistently. However, a supervisor, Tony, specifically told me that eHarmony doesn't bother to follow this standard privacy practice.
Does this matter? Should I just drop it?
