I don't know Babycat from the next WL/ML but i have no doubt she is real. I dont even have info from a 'reliable source'.
I have seen wl/ml on here being active from time to time and it would appear punters want to get into dick swinging matches trying to woo the heart of the ml/wl in question, or at very least try and have their way with them.
Why do ML/WL participate in this forum? I dont know for certain but some would be attempting to drum up business, others are intrigued by what us punters think. Babycat does provide AR's of sorts. I think she is genuinely interested in what is going on in the forum but also think that she wants to understand what a punter is seeking in an effort to improve business.
