"I can spot Internet Trolls a mile away."
And we can spot a spammer who always posts a link to his pages. About
which he has boasted how much money he makes by people going there.
"Until you post the complete citation, I am NOT going to waste any of my
time on what at best would undoubtedly be fraudulent research and what at
worst is probably just Total Bull."

With your new interest in science, you will have to know how to use science
