KZ, this is what the iHub rules say about statements like this:
"Veracity of posts and credibility of the author is determined by the reader."
If you know it can't be true, then you can call it as you see it, information wise.
After a while the source will naturally develop a reputation as to the "truthfulness" of the posts.
But the rules also say, "attack the post, not the poster". So calling the poster a liar is not allowed. Calling his post a lie is.
Just a friendly recap of the TOU's.

Don't take my word for it, Do your own research! Then you will know it's true!
