And I think also -- to add one more point I ought to have made in the last post -- that the important point is, as always, to treat others the way you'd rather they treat you. I think many of the same authors who over-self-promote (like whichever unnamed author we're discussing) would cease to do so if they thought about the end effect. If you don't like being spammed by someone with a product to sell, don't spam others just because you want to sell your book. Elementary politeness...that's what it's all about. Good books take time to sell and catch on, and hassling people about your book is the best way to alienate them, IMHO, anyway
