Another problem: what is a barebacker? It's not particularly clear-cut.
Plenty of EE girls (especially Romanians) have bareback on their profile without apparently knowing what it means. Some will probably offer it at an extra price (despite claiming that it's included), others won't. Some British girls offer it as a paid extra: if it's £20 extra, they can be classed as "barebackers", but if it's £100 extra, essentially they aren't, as hardly anyone would pay that much when they can get it cheaper elsewhere.
Then there are those who might offer it as a special treat for a regular. How regular, exactly? If it's "anyone I've seen at least once before", she's a barebacker. If it's "only you, because I've seen you dozens of times and we've already had several free overnights", she's basically your girlfriend.
It wouldn't be particularly easy to decide who should be discussed on such a board. Both the clueless EE girl and the semi-girlfriend might be mortified to find themselves on it!
