If you're an acvtive internet marketer you sure must have come across people selling PLR articles, PLR ebooks and what not at dirt cheap prices or even free...
For the uninitiated, PLR = Private Label Rights
That means, you have the authority to modify the stuff according to your need and also have the rights to resell that product at any price you like.
In the last few weeks I see an influx of such PLR stuff flooding the internet. Many people are just giving away PLR articles on various niche topics free in return for your subscription to their email newsletter

. So you get marketing emails from them all the time. Plus, you don't feel like unsubscribing them coz once in a while they send a free gift too (another plr stuff!)
What do you think of such marketing tactics?
