matejbusic, your post might have more credibility if it wasn't directly copied off of websites selling "natural" beauty and anti-aging products, since it can be easily construed as scare tactics specifically designed to up sales of their own pg-free items (just in case you are not aware, it was also posted word-for-word on a site full of other highly...debatable...information as well).
As an additional heads up, your credibility might also be better served if you just choose one thread to which your reply best applies, and only post it there. Yes, spamming it as a reply to a bunch of different threads all over the board might multiply the raw number of people who see your reply. However, it doesn't increase the chance that people will believe you, and in fact it will most likely just increase the probability that people automatically ignore your posts as "yet another one from the fanatic who spams the advertising from those anti-aging sites in every thread."
