On http://www.nanog.org/filter.html there is a small list of ISP filter policies.

Does anyone know a more comprehensive and up-to-date list? Especially: are all ISP filtering according to the minimum allocation?

*all* ISP? At best, you'll find "most", or "enough do it that trying to advertise less than the minimum won't work well" - which is what you really care about. About the only thing that "all" ISPs agree on are the de-facto requirements to plug the router into an appropriate electrical supply - there's probably a lot of mom&pop ISPs out there that don't do any filtering of BGP because they're so small that they don't need to talk BGP to their upstream...
