This is just an inkling of the goofy stuff and potential landmines lurking within their network. You should open tickets, escalate to management, and abandon this provider ASAP.
I don't think it's option 1. We've been a direct Level3 customer for several years and though we're not filtering on RIR minimums yet (ask me again in January :) we do have some basic sanity filtering in place. Level3 isn't sending us anything longer than /24 and hasn't at least in recent history (according to my distribute-list).
