He is, on Second Life.

Seriously though... I've not seen any discussion of the application of
"allowas-in", a valid neighbor configuration under certain
topologies/scenarios, as relates to impact today.  Also, I'd agree
announcing other peoples' ASNs, without their permission, is in bad
form.  It's okay he's doing it to you, but I bet Randy would be a lot
less smiley if you were to announce random paths with 3130.

You should've seen the email storm and panic created when I prepended an AS to avoid a blackhole. I got the right people interested in talking to me at least, but boy-o-boy were people confused about what I was doing.

I guess the problem is that AS PATH is overloaded and people forget that the primary purpose is loop-avoidance. Everything else is secondary and much like reading Received headers in SMTP mail, you really should take everything after your direct neighbor's AS with a grain of salt.
