Sounds like misconfiguration.  Have you tried contacting them and 
explaining the problem?

&gt; I have a few customers' customers, who appear at a local IX. &nbsp;Due
to <br>
&gt; the MLPA-like nature of the IX, I hear their prefixes both at the
IX <br>
&gt; and via my own transit customers. &nbsp;I normally use localpref to
prefer <br>
&gt; customer advertisements over peers' advertisements.<br>
&gt; <br>
&gt; There is a customer's customer who is advertising more-specifics at
the <br>
&gt; IX (and using a different source AS, to boot). &nbsp;I can think of
a couple <br>
&gt; ways to prevent hearing these, but thought I should ask for suggestions
<br>
&gt; first.<br>
