Yes. Like I said, I know what they "intended" to say, but they didn't use the term correctly.
Those same people are the ones who respond to an offer to subscribe to a newsletter with their email to get a product for free and then when they get the first issue of the newsletter click the "report spam" button because they didn't remember subscribing. Nevertheless, whether they remembered or liked it or not, they subscribed, so they falsely accused the newsletter publisher of spam.
I believe the term spamming tactical training is meant as a metaphor like comparing it to the difficulty of trying to read your e-mails when your inbox is full of junk mail.
