Should I worry about bogus route registry entries?

[Florian Weimer <fweimer () bfk de>]

Recent events prompted me to look at a few routing registries for
information on prefixes dear to me.  I have to admit that I don't like
what I see.  There are quite a few RRs which publish illegitimate
shorter prefixes which cover the ones I'm interested in.  A few months
ago, I looked into this issue for other reasons, and had one or two of
them removed, but this is a bit tedious -- especially since some of
the databases are not public and are only revealed by other RRs.

Should I care about this on-paper prefix hijacking?  Is it worthwhile
to set up some kind of monitoring?  Is there a blacklist of RRs which
are known to deliver mostly bogus data to other RRs?
