I wouldn't bluntly state it's a stupid character biography to put, but instead, I'd use the term, weird; at least for this type of platform. It's not an act of stupidity, just for either attention or socialization in the wrong way. Some people like the "Lilly" person here, finds it easier to try to seek that attention through requesting a "mate."
With younger audiences (doesn't matter what age) doing this the most, it bums me out. It sounds like something you would read for a dating service website when someone says, "Will you be my mate?" when they've only known you for four seconds.
Also, I do find this funny, lol. Sorry, sometimes I ramble. ^^''
