But now you are like ms/google/letsencrypt. We decide how you should setup your servers, we decide how you setup your dns, we decide you are not allowed to block the amazon cloud etc.
WTF drugs are you on, my organisation my rules.
What education did you acquire? With your logics you configure your spam servers like this "I don't want to receive spam, so if the last octet of the connecting ip is uneven, I will block it"
and who said anything about not allowed to block amazon, I have a couple of amazon class C's blacklisted here, dont answer that, it was a rhetorical statement.
No way to little volume. You should focus on that this system is not updating its data, maybe because it is on a shared network that is being blocked because of unnecessary scraping?
This is off topic, so for my last...
I dont care how big or little ones volume is, it's the quality thats taken into account, and if you're on a shared IP, its the risk that you elect to take, that aint my problem, have a great week.
Your system reporting false positives, that is what I am trying to tell you!
