I didn't open the emails. The domains were apparent without doing so. Of course, who knows what the real domains are. Was not going to open them to find out. I highlighted them as spam and deleted.
If you are getting spam like these fake Amazon things we all get them from time to time if I have not ordered anything from Amazon or I'm not dealing with them in the last couple of days I just delete the emails without opening them and call them spam.
I'm not a betting man but I'm going to bet that radio reference is not one of the sources that you have to worry about them giving out your email as they have stated clearly in their policy they don't.
You'd be surprised some of the crap I see come in on my designated spam email. I have a three tier email setup. A very private email that I literally don't use except for family and very close friends, a business email for my clubs and boards, purchasing things, official business.
Then I have an email address that is pure spam. I use that email address when I don't want someone to have my email address but it is required to go further. I check that about every two weeks and just delete everything. I would never be contacted with anything important on that address. Well good luck, I hope your spam stays to a minimum.
