AS Leakage

Hello;

   In our BGP table, there are this morning the following AS's :

 AS  64610 :    1 prefixes :    1 prefixes supported :   3 hops : as path  1239   209 64610
 AS  64615 :    2 prefixes :    2 prefixes supported :   3 hops : as path  1239   209 64615
 AS  64616 :    3 prefixes :    3 prefixes supported :   3 hops : as path  1239   209 64616
 AS  65008 :    3 prefixes :    3 prefixes supported :   3 hops : as path   145  2200 65008
 AS  65102 :    3 prefixes :    3 prefixes supported :   3 hops : as path  1239   209 65102
 AS  65209 :   12 prefixes :   12 prefixes supported :   3 hops : as path  1239   209 65209
 AS  65498 :    1 prefixes :    1 prefixes supported :   3 hops : as path  1239   209 65498

In the MBGP table for multicast, there are

 AS  64580 :    9 prefixes :    9 prefixes supported :   5 hops : as path  1239  5511  2200  2074 64580
 AS  65001 :    1 prefixes :    1 prefixes supported :   4 hops : as path  3300  8933  2200 65001
 AS  65498 :    1 prefixes :    1 prefixes supported :   3 hops : as path  1239   209 65498
 

I thought that these AS's were not supposed to be advertised globally.
Is this really a problem ? Is it worth the effort to track the sources of these down and
try and get them to remove them ?
