I hate to say it, but I don’t believe reporting these is worth it.
I don’t see any harm in doing it. I’m just not convinced that reporting these does anyone any good, and it simply boils down to a waste of your time.
I’ll give you a couple of reasons why.
There’s just too much spam
The addresses you listed1 get so many reports of the spams and scams that what you’re reporting is just a drop in the ocean.
It would be incredibly rare for you to give one of these sites a notification of something that hasn’t already been seen and reported by someone … repeatedly.
There’s rarely any new spam
If you take a look at your spam folder, you’ll also notice that you get multiple copies of the same spam or scam over and over (and over and over) again.
The messages here are so obviously spam that it’s just amazing that spammers and scammers even try in these situations. Now, multiply that by the number of users on the planet, and you can see just how much spam is out there.
Everyone already gets spam
Remember, the people working at these agencies are also getting spam, too; not just from honest people forwarding what they found, but because they have email addresses that are tapped by spammers and scammers. In fact, by spamming the reporting email addresses, the spammers are already, in a sense, reporting themselves.
If doing this makes you feel better about spam and scam and if you’ve got the time, carry on. I just don’t believe it makes any difference in actually stopping spam and scam emails from arriving in our inboxes.
