Funny thing about the Internet -- so hard to prove anything via the "he said, she said" methods that might work well in real life... where people actually know you.
Here, you'll just have to face the harsh reality that nobody believes you without hard evidence... and even then, they may not care. To many in cyberspace, we are merely words on a screen... what could you possibly have to prove to that?
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
