16387 is a uunet customer, it seems, who's only annoucing (now) 2
prefixes... Robtex seems to support them only having a single upstream
(701). I think 701 still prefix-lists all their customers.

You saw this through 3303 without 701 (it seems?) in the path, The
orignal prefix looks actually like in the path: 34533
that looks like ESamara trying to poison their paths toward 'healthy
directions, LLC".

maybe ESamara saw something they disliked from this part of the network?
