I reply to most, if not all, whether he wants to book me or not.
I wouldn't respond to someone trying to get a freebie. Nor to someone seeking something I don't offer. On the whole, the pm's I've received have been well behaved, well intentioned pms.
PMs I will ignore are the ones that are the equivalent of unnecessarily graphic phone calls where I get a sense there's little intelligence behind the approach. Just wistful thinking about a desire to spin on the business end of my strap-on, or be turned into my bitch. Perhaps I expect too much to assume that every guy that books me would have a brain between his ears so I instantly blank the obviously brain-dead.
