Name.

On a dating site I'm on I got a message from someone called 'Piscesbutterflychick'. She seems fine but I couldn't possibly respond to someone with a name like that. Someone (and that's not going to be me) should tell her to tone it down a bit.

In the same vein, I once helped a woman friend of mine by getting her to remove all the references to her cat from her dating profile. It worked.
