Everything has pluses & minuses. The as7007 debacle was actually made far, far worse by Sprint's policies at the time, including a "-smb" (thanx, Dorian) build. Vinny may have made a major boo-boo by pumping BGP through RIPv1 then back into BGP, but the fact Sprint filtered only on AS path _and_ had an IOS which ignored withdrawals was the real killer.
Let's work on the primary protection of the INTERNET. When you were at Verio, you were driving a policy that you wanted, despite being clearly and objectively a tiny minority of the population in question. It might have made the Internet safer, but it had lots of bad side effects, including making it so that large networks have an advantage over small ones. Since those "small networks" are frequently the people paying the bills, and I am here to make money, I am not terribly happy with such policies.
A quick list off the top of my head: BCP38, filtering customer announcements properly, putting pressure on networks that needlessly deaggregate, ensuring information (e.g. "your 6500 is about to crash") is properly disseminated, etc. These will have far larger impacts, disadvantage no one, and will not lose you business like your previous policies did. Everyone wins.
All that said, I still abide by my primary rule: Your network, your decision. I am arguing for things we can all agree help everyone, not a select few.

Ad hominem implies I was going after your character without facts. However, the statement above _is_ fact - at least I believe so and given the private replies I received (and especially who replied), I am not alone.
Also, you calling an ad hominem attack "pathetic" is hilarious in more ways than I can count. (Again, not ad hominem. It is trivial to objectively prove that statement hypocritical at least, which I find amusing.)
