Fellas, here's an idea: if you think a gal you're reviewing didn't earn a "yes" recommendation based on your expectations, don't give her a "yes" thinking someone else would enjoy her company. Giving a yes recommendation when you weren't satisfied leads others to do business with people they might want to avoid and cheapens the value of the yes recommendations earned by some of the great ladies on ECCIE.
If you're worried that giving a bad review will hurt your rep, then your good rep was never that strong. If you're worried about a bad review causing drama, then share the drama with the everyone else so they'll know who to avoid.
End of rant.
