"the IP may be renewed every day or every hour)"

What a coincidence! Right now from my phone on my carrier's network while traveling in the UK I am unable to reach https://cheapskatesguide.org My phone's IP address is likely on this guy's blacklist of 56M addresses. So I am forever going to remember whatever service this website provides may be arbitrarily unavailable unless I'm on a know good IP address. Overly aggressive blacklists like this are lame, make you lose customers, and go against the Internet's fundamental principle which is about the ability to exchange information with anyone in the world.

I will also add the mentality of choosing to allow or deny access to your service for millions of IP addresses at a time based on some ill-defined rule or based on the service operator's whim is EXACTLY the same mentality that lead us to the current difficulty of running self-hosted email/outgoing SMTP servers.

"Oh because your dynamic IP address was assigned to and used by shady guys 2 years ago, now you cannot access my website, or all your emails will be flagged as spam."

Don't do that people.

Not everyone on the internet is trying to get customers though.
