I had resurrected a similar thread last year:

There are sloppy networks out there. If it was a big enough problem all
you'd need is a few key networks drop those prefixes and we'd have

The results of the fat fingers showed that there are an astronomical number of private ASNs in the wild. I checked the CIDR report, and those ASNs are shown there in a specific Bogon ASN report, but I’m surprised that as far as I can recall, there haven’t been any efforts made by the good netizens around these parts to bring awareness to this issue.
