Another tip - always set default profile gender to "Female". Women are less prone to feeling alienated by gender, but guys typically get uncomfortable with being labeled as a woman and will change it

Unless you're operating a World of Warcraft forum :)

In a way I think this is less intrusive (and clever). These are merely "suggested defaults" that never actually get displayed on the user's profile. Actually using bad defaults may have the undesired effect of people not changing the bad default.

This is akin to ridiculing your customers until they cave in and bow to your bidding. I don't think it's good to treat your users that way.

In Garry's Mod the default name was "Mingebag". That's very much reflective of Garry's sense of humour...
