How about a system where you can add a caption to a user and others can see the list of captions and can choose one to copy, the most used caption is displayed, so anyone can nominate any caption and people essentially vote for the one that fits best - perhaps also a minimum amount of copies/votes needed before it is shown so people can't just put anything they want on un captioned users
It's bad enough that this forum is a scammer haven. Adding options which pretty much amount to popularity contests will remove whatever illusion remains that it's a place where serious Bitcoin enterprises hang out and relegate it once and for all to the "fan site" category. We don't need to do things which make it even more like an AOL chat-room for petulant teenagers than it already is.
