Hi Cedric,

If someone put you in theyr as-macro, it's maybe because they give you transit. Maybe the first search step is search all your transit as who are in this list and check theyr as-macro (get them over peering-db)

We do not pay for transit from a Russian-ISP, although our ASN is referenced in their AS-SET. We already tried to contact them multiple times but they do not respond. I’m aware that this is not a practical issue, but still it's wrong. Regards Dominic
