Filtering the bogons does help, and everyone should perform anti-spoofing in the appropriate places. It isn't, however, a silver bullet. it's necessary but not sufficient. anti-spoofing is useful, but vastly insufficient, and hence not necessary anti-spoofing eliminates certain avenues of attack allowing one to focus on remaining avenues, and hence (as Vix stated) is necessary but not sufficient.
it turns 1% of the technical problem into a massive social business problem which, even if it was solvable (which it practically isn't), would also be addressed by technical solutions where no spoofing is involved. but it would provide a lot of fun and soapboxes for wannabe net police and vigilantes. randy
