pitza you are right about reporting them to companies such as AWS. This has been a big issue I’ve been making a little bit of noise about on social media (Twitter).
However, all of the times I have reported them, I have had success.
But we all have different experiences.
Regarding the paid account, that could be a good idea. I mean, I have a paid doman for my website and I’ve created an email on that domain, and there are advanced spam filters. So I partially agree here too.
