A brief look makes me reach the same conclusion as you did. Pure waste of time.
Consider statemets such as this:
"More than an intuitive nonsense, Einstein's Theory of Special Relativity, it would seem, legitimised a century of stupidity. Sound like a person with a great deal of ambition who has failed calculus in college.
Or this:
The physics that was taught in the 20th century was supposedly based on Einstein. In fact this is not the case, there was a conspiracy against Einstein and his theory was replaced by the physics establishment in 1925/ 1926 by a false theory that is still called Einstein’s theory. The conspiracy started before World War II, and was maintained after the war because of Cold War tensions of wanting to keep atomic secrets from the Russians, and after that it evolved into a doctrine that prevents certain experimental research being carried out that can prove the 1925 theory as being wrong.
Does it not look like not-so-mild case of paranoia?
Indeed it does. However, not all cranks are so easily detected. Tom van Flandern appears to be quite sane and rational, and a regular scientist to boot. Yet the general relativity theorists dismiss him as utterly wrong-headed. I'll take their word over his because they are an overwhelming majority and they can't all be part of a vast conspiracy to suppress this man's findings. But I'm way past out of my depth in trying to form my own judgment.
