Actually, from where I'm sitting AS719 still looks to be in bad
shape. However, as you say they are just one of many. I encourage
everyone to take a quick look through
http://www.employees.org:80/~tbates/cidr-report.html#Aggs
You may just see something youy can clean up.

* It looks like AS 719 may have cleaned-up their act, but there is still a lo
* t
* of garbage in that section of the report. Most of them seem to be subnets o
* f
* /16's that all have the same AS path and therefore have no reason to not be
* aggregated. 168.108.x.y, 166.102.x.y, 152.166.x.y-152.172.x.y, 129.81.x.y,
* and 139.175.x.y are the most obvious offenders - all of the components of e
* ach
* are singly-homed to a single AS path (yes, AS 1 has a couple of small ones
* not listed above - I'll see about chasing those down). Others, like
* 161.11.x.y, 138.87.x.y, 137.15.x.y, 137.98.x.y, and 143.233.x.y appear to
* be multi-homed but still shouldn't need to be propagated to the global
* Internet.
*
* If you're going to accept CIDR block subcomponents from your customers for
* load-balancing or other purposes, please set community "no-advertise" or
* otherwise prevent them from leaking out to the rest of the net - everyone
* else doesn't need to see your trash...
