DSL providers are becoming very bad about this. Someone pointed out to me off list that CAIS had carved up PSI's /8 into over 500 /24s.

Well at least we don't have to go too far to find the guilty party. :P

Those are the GlobalCenter datacenters being converted into the Exodus network. It looks like they are leaking a sizable number of /32s /30s etc, and since its GBLX space I'm assuming its stuff that used to be aggregated into a single announcement.
Email sent to: ipadmin@gblx.net, huberman@gblx.net, ip-eng@gblx.net, scarter@gblx.net, bgp@gblx.net, bp@gblx.net on June 4 - everyone responded that the problem was forwarded to Exodus and from there it disappeared into a black hole. Basically, after having sent out dozens of emails over the past 6 months I have come to the conclusion that there are a few out there that will fix things when presented with the problem. But the vast majority either don't have a clue, don't want to have a clue or couldn't give a damn that the routing tables are increasing in size. -Hank
There is no attempt to measure aggregation - that's the job of the CIDR Report. This simply looks at the prefix announced and if it is outside the above limits, it is counted. Makes very interesting reading...
The one interesting pattern I noticed in the rampant /24 abuse was non- contiguous announcements. It's likely that this kept them off the CIDR Report and any other scans which only looked for contiguous announcements. For example:
1.2.3.0/24 1.2.5.0/24 1.2.7/0.24
