We have rules on BHW put in place about not begging for review copies unless it is specified by the OP that he or she is giving out review copies. Let's be honest, most people don't read the rules. In order to deter people from posting these messages on BST threads, maybe when someone reports the message, the mod can edit it to say *Comment removed for violating the rule of asking for a review copy* or something along those lines. People learn better by example. If anyone has any better remedies I'd be interested to hear them.
