    Hi

    We blocked some prefixes belonging to AS14037 (rackvibe llc) due to
    their hosting spammers.

    Rackvibe decided to nullroute us back in reply - thats up to them I guess

    Only they're dumb enough to inject these blackhole announcements into
    the cloud, and various other networks are picking up on these
    announcements

    TIA for filtering these out at your end

    Our IPs are below - at least 208.36.123/24 seems to be announced as a
    blackhole route by rackvibe -

    205.158.62.0/24

    203.86.166.0/24
