The King Of Spam for 2019: M247
The King of Web Spam and Blog Spam for 2019 is officially the ISP
M247 Europe SRL
or by whatever other name they appear (or whoever is using their services). Spam sources mainly from Sweden, The Netherland and Germany. We have tried to battle this for our sites, with some good results. Over 10.000 web spam per day in December (in 19 websites) from IPs all over Europe, using contact forms and blog comments.
So we declare M247 as the KING of SPAM for 2019 !!
