I've had a _few_ spam spews here which came from Linode IPs, but very
few. Other IP blocks in Brazil, Poland, Italy, DigitalOcean, etc.
harbor many more.

Be that as it may, the support folks at Linode are exceptional, and go
the extra mile for me on any problems or questions I may have, whether
it's their issues are someone else's.

I've got a lot of sweat equity into programming against their DNS API,
and have an IPv6 /56 subnet from them which provides v6 addresses to
our SOHO LAN. I have too much on my plate to make a major move,
including 80 or so domain names on their DNS.

The Linode support folks went to bat on this particular issue and filed
a delisting request with Microsoft on my address, or the /24 containing
it. I've done the same from my end.
