I'm not game to check out these links but you could have posted all these links in the one thread inside of starting four separate threads.
I did 4 threads cause I was on my tablet had to cut and paste each time. Why are you not game to click on links? Thanks for kind words, not! Oh tyrannical dictator of the forum. I am sensing you are like a sheep; afraid of anything foreign to the small little flock world of your mind.
There's been instances where malicious links have been posted on the forum - it's a safe browsing habit to not just blindly click on an unknown link. Posts that just contain a single link look spammy - better to write "something" in the post about the material you are linking to their than just a single word subject. Many members wouldn't know that the word refers to a medical condition usually associated with ingesting excessive or poorly prepared colloidal silver, so there's no reason for them to click the link.
