I doubt any business would fall for that since they already receive false complaints, bad reviews, negative reps etc from the new competitors who pay people to do just that.
They do. Such scams are a big deal for the scammers.
All they need is 1-3% response to get wealthy and they send millions of emails each day.
Wow really? but don't these businesses who pay to these scammers realize that as soon as they run outta money they'll contact them again and ask for more?
