Yes I answered I do NOT block AWS subnets only AWS IP addresses that try to gain access to my servers without any invitation.
I was not aware that AWS needs to probe my servers creating 404 errors more than 3 times over 3 different occasions, merely to allow me to renew a certificate.
Nor was I aware that they had to be allowed to try to guess the passwords of all the users of my mail server.
I don't care if it's Amazon that's doing it or their users. IMO if you want to run a hosting company you should ensure that you don't allow spammers and hackers to be operators. I think EVERYONE on Digital Ocean is either spewing spam or a member of a bot. Wgat do they do about it? NOTHING. Seems AWS has the same policy.
"We don't care if you rob old people of their life savings as long as you pay your subscription every month. F. the old age pensioner, they ain't my problem. I need a new 'plane to show my support for global warming."
IMO companies should be trying to STOP cybercrime, not actively encouraging it.
