Depending on granularity, I would expect that "small" blocks - say /22
and smaller - may get listed in the PBL as part of a larger assignment
sub-allocated by an ISP acting as an LIR or equivalent.
I wouldn't be at all surprised to see smaller "upstream" ISPs just
listing their entire RIPE delegations, regardless of the sub-allocations
they have made. It's incorrect, but very easy to do - if you have
several hundred blocks to manage.
