At various times, different sites have told me about how “mature” their community is, based on age statistics that they have. Apparently, they didn’t think that it was too odd that quite a few users were “81” or “100” or “69”.

Not only is it common for users to lie, but there’s an entire population of users who purposely invert their age. Thus, if they’re really 18, they mark themselves as 81.

To get a clear picture of this, go to myspace and do a search for all users 51-100. [I say myspace because it’s allows for an easy age search.] “Bill Clinton” is the only one on the front page who looks older than 51… most look like teenagers. But apparently, there are 4064 people over 51. Hmmm.
