hosted-by.leaseweb.com: Research, Ban
I have had a couple encounters with this spammer, but only one where they left an actual IP for me to ban. The rest I have only the host name, much more difficult to track down.
Research them and you will know they are a formidable entity to track and ban. There is a lot of IP ranges to cover.
Observation:
hosted-by.leaseweb.com confirmed because they spammed me, so I have their IP address
