[Microsoft spam reports go to the sewer?]

Still the same issue: 

Finding IP block owner:

Routing details for 40.107.244.53
[refresh/show] Cached whois for 40.107.244.53 : abuse@microsoft.com
Using best contacts sewr@senpluspluseop.onmicrosoft.com

If reported today, reports would be sent to:

Re: 40.107.244.53 (Administrator of IP block - statistics only)
sewr@senpluspluseop.onmicrosoft.com

[Help requested: abuse contact seems to be the spanner himself]

We get many fraudulent bitcoin spam mails from the same server group 45.144.215.0 - 45.144.215.255. 

Each time, another IP from that group is beeing used - abuse contact for all used servers is ralfnoack1982@gmail.com. I suppose, this could be the spammer himself, since reporting is beeing ignored. 

What kind of reporting makes sense in this case? I allready figured out, that the servers are hosted by nshostu.ru - so i instead started to send my reporting to abuse@nshostu.ru. Any other ideas?

Thanks for your help! 

Best regards 
Sam
