I got to know that this WES is really a bogus pNLA from Poland using ASN7170
when peering with ATT-LABS-EUROPE and VIAGENIE. The administrator address is
probably firstname.lastname@example.org. I am also sending Cc to ASN2020
administrator new address (email@example.com) who has just cleaned the mess at

Again IKARNET->false_WES path but maybe ZETs (firstname.lastname@example.org) fault in this
case. Cc to him also.
thanks for announcing/letting me know, I was able to mediate to some extent
PS. Just now the bogus routes disappeared completely, I hope that forever.
