anyone else seeing very long AS paths?

I just see it from 47868 and I just filtered it so it would stop blowing
up BGP sessions to customers.   In our case we are only seeing the
prefix from level3 which prompted me to create a route map to block it:

ip as-path access-list 500 permit _47868_

route-map as3356-in deny 1
 match as-path 500
