I've seen this.. this is from a topic I started on my forum sometime last year..
These are screenshots of a forum that I was on recently. Now, I could tell by looking at it that the stats were OBVIOUSLY fake..
But my curiosity got the better of me and I decided to disable javascript to see what the actual stats were.
The stats weren't too bad at all and while very little content wouldn't necessarily deter me from joining a forum, I am not a fan of deception and so, I didn't join at all. I think it is better to be honest, than to make yourself look worse by lying and although this is far from the first forum I've seen with fake stats, I honestly don't understand why some admins do this..
