Getting rid of spammers is something that is so difficult to accomplish because these folks execute their games along with technology. So, they are quite smarter than you think and, thus, are hard to play any game with.They have a lot of articles online, asking people to pay for one service or the other.
I've personally been a victim of these spammers when I first started out online. Their websites are better designed than those of the genuine programs. So, it is quite hard, particularly for newbies to identify such websites. For instance, it took me about three years of starting online before I could identify spammers' websites and genuine ones.
