The way I view this profile business is that there is indeed an "official" profile similar to what the OP said that goes around craigslist type sites. Both those looking for slaves and those looking for masters.

I think the point is not to say that its negative or they are damaged etc. But that this certain "type" is soooo submisive ie. slavey in such a demonstrable way that these circumstances have happened to them because they are lacking some sort of assertiveness etc. that those who are less submissive might have. It's also a way I think to wave your "Knight on a white horse" flag. Some woman want to be rescued. Some Doms enjoy rescuing and building up a person from those circumstances.

I wont say a large amount of people fit this. But there is definitely a circle of people this fits.
