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
208.36.123.0/24
203.86.166.0/24
65.49.50.0/24
65.49.50.0/24
64.71.166.192/27
64.62.181.80/28
