yep... First one mines 1.5 DTC in about 2 minutes. I wonder how is that possible. With what machine...probably botnet? And if yes should he be baned?
Ban only if you have thousands of connections mining to a single user/wallet
I for example have a network of nearly 1000 machines that I look after and could easily set up a mining operation on them legally.
So also not always will it be a botnet, however my case is very rare. There aren't that many admins of networks of such scale.
You can see which worker doing what and a top 100 list
