That's too bad if she is very good. I get why she would want to be fully prebooked, who wouldn't. But realistically, how many are? With legit reliable clients. Most if not all seem to advertise everyday there here. They wouldn't do that if they were full.
Has she even been here before? Are there any reviews here? The other board can be a little generous..
Doesn't it take awhile to build up some regulars? Lots of guys can't book to far out. An ad on bp a week out wouldn't be enough imho for someone newish.
Think about girls like Irena and Amy. They come and knock the socks off the boys. Word spreads fast.
