I prefer the approach of disaggregating only when needed, not as a preventative measure. There are tools that can help with automating this disaggregation (ARTEMIS can do this, for example).

How does the community feel about using /24 originations in BGP as a
tactical advantage against potential bgp hijackers?

All of our allocations are larger and those prefixes we announce for
clients as well usually are. But we had a request recently to
originate everything as distinct /24 prefixes, to reduce the effect of
a potential bgp hijack. It seemed a little bit like a tragedy of the
commons situation.

Is this seen as route table pollution, or a necessary evil in today's world?
How many routers out there today would be affected if everyone did this?
Are there any big networks that drop or penalize announcements like this?
