I have noticed this more and more lately and I am really wondering about this... Have you noticed that a thread will be posted about any kind of topic. Engineering, physics, politics, etc...It doesn't matter. If you get the right type of topic, there is, a lot of times, someone that comes along with a 0 or 1 post count to defend a certain position. In the engineering or physics side, they are usually free energy whackos or space elevator J.O.s. These people have never had anything else to do with PF or any other discussions yet they pop up at somewhat opportune times to spread their opinions. How do people manage this? Do some people sit out there and search the internet for their pet topic just for the opportunity to spread their word? Is there some kind of internet search program that constantly scours for some kind of key word for them? When it pops up, a bat signal goes off and they don their cape and utility belt and swoop in to save the day.
