I don't have any evidence, because I don't use Facebook. Furthermore, I never made any claims to provide evidence for.

Do you have evidence or source for the claim you made? Or are you just here to call people silly names and pass anecdotes off as fact?

Anecdotally someone may have evidence of poor performance. Assigning a specific number to its statistical probability based on that anecdotal evidence is where the problem lies.

That's not how statistics, or debate, works
