Unfortunately, this is true. Some people just don't care about conversation and just spam. I would suggest to those people to get a real job out in the real world. It's a long process before your account is high enough in rankings to make decent money (unless you purchase an account).This is the best point.

2) Be controversial. Say you opinion and speak your mind about the topic at hand. This will result in possibly heated debates that can get you really enticed in the conversation. You may even forget you're being paid to post on this forum.
I know one person here who are spamming in every thread, and trolling users with stupid answers and questions. Making new Post with stupid non-crypta themes or posting pictures. Some times all page is full of only her posts! And what we can do with such users? nothing
