Am I second guessing myself since I sent this email to a couple of friends. OR am I correct?

I 'think' a reason that I have been getting so
much spam lately is because my address is being harvested and used by spammers.
They can do that VERY EASILY because my address appears every
time you send me an email. Not ONLY me, but EVERYONE you email using the same
procedure "could" be receiving spam. It ain't no trouble for you to simply use
the bcc(blind carbon copy) line INSTEAD of the TO line when you fill in the
address of those you want to sent an email to. NO ONE, including spammers, will
see who is getting your email. Believe me, it is far far safer IF you will do
this. I may have to consider BLOCKING your emails in my email account to help me
avoid getting so much spam. I know of no other way to help me----AND YOU. I
enjoy getting your emails but NOT the spam!!

And as usual, TIA.
