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
Leaseweb Deutschland
46.165.250.0 – 46.165.251.255
46.165.251.153
hosted-by.leaseweb.com 108.59.8.80
162.210.196.130 hosted-by.leaseweb.com
Leaseweb is scraping with an anon bot called “Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)” and a bot “-”
91.109.16.0 – 91.109.23.255
95.211.142.0 – 95.211.144.255
best-hosting.simplexhost.net is a prolific content spammer, and a true chameleon, as it changes IP addresses very often. Look up its hostname and you will get 62.210.24.146, but ban this ip or even range and best-hosting.simplexhost.net spamming simply will not stop. This is good for fooling anti-bot engines.
Observed:
62.210.24.146 62.210.0.0 – 62.210.127.255 Iliad is a spoof and has nothing to do with best-hosting.simplexhost.net
contabo.host is a consistent content scraper from Germany. I’ve been banning IPs for a while, so thought it best to go for larger ranges. They are a hosting company, not an ISP. kontrollprozesse.contabo.host, a content spammer, was added 2016 Jul 27, and includes a larger ban range.
Observation:
vmi60316.contabo.host 5.189.137.81

vmi32368.contabo.host 213.136.84.244
m1131.contabo.host 178.238.239.246
kontrollprozesse.contabo.host host command maxed out and returned over 256 entries (2016 Jul 27)
