What I am suggesting is that the community at large needs measurement
data, rather than individual network operators (which already know if they
do or do not implement BCP38). Only with a long list of operators that DO
prevent spoofing and a list of those that DO NOT, backed up with a decent
data set (enough measurement points, enough measurement tests, across
enough time, with an openly shared methodology), can the community start
to encourage non-adopters to change their position. Just my two cents
though...
