   works well or you see issues with people who have 10+ prepends on some
   peering routes calling you to not send traffic via those circuits?


OK. I admit being perplexed.  Under what conditions will somebody have that
many prepends and you *still* end up routing via that path if you have
another path available?

I guess if they were silly and prepended themselves 10 times and then
announced the result to the upstreams of *both* paths you have available...
