I have my own system of IP reputation whereby if an IP address hits one of my systems with some probe or scan that I didn't ask for, then it's blocked for 12 months.

P.S. just to add a note here that I have been blocked out of my own systems occasionally from mobile / remote IPs due to my paranoia-level setup. But I treat that as learning / refinement, but also can accept that as the cost of security sometimes.

I think all the points about IP reputation impact are well taken, but as someone who had to deal with the RIRs at an ISP before and who now works at a firm that buys blocks, I would 10x rather operate in today's environment than in the old RIR environment. It's transparent and predictable by comparison.
I never had much faith in reputation to begin with, and the residential block issue is muddied by the fact that large-scale residential proxies already make that an unreliable abuse check.

Banning IP leasing would concentrate power in the hands of those who have large IP blocks. Makes one wonder what the real motivation behind this post is.

Good. GeoIP should be dead, and "IP reputation" should be meaningless garbage.

acidvegas is a pretty shady guy himself, running an IRC spam network pretty much in broad daylight. I don't know what to make of this connection, except he probably has a reason for posting this that's slightly more nefarious than sharing some interesting knowledge.

Hard to take much of this too seriously, since there are total misrepresentations like this:
> Their automated reputation management system actively maintains the "cleanliness" of leased IPs, ensuring they don't end up on blacklists — which is a polished way of saying they launder IP reputation as a service.
No, as someone who leases some unused blocks via IPXO the entire point of the reputation management system is to centralize abuse reports for them to respond to so they get categorized, tracked, and handled. If more than a few come in the lease gets canceled as that’s against the AUP. I’ve had folks lease a /24 and try some dirt with it, only for IPXO to pull the route within hours. Far faster than I could have responded.
As an ip holder I don’t want my resources being abused and added to blocklists so this is important to me. I do indeed plan on taking them off the market for my own use as my IPv4 usage needs increase over time. Until then, leasing them was a way to be able to justify the money spent acquiring some blocks before I got entirely frozen out forever by the hyperscalers and giant companies of the world eating practically every large block they could get their hands on.
It’s future proofing my digital sovereignty. IPv4 scarcity is used by the AWS of the world to reduce competition and choice.
Geolocation is such a stupid game as it is. I’m in strong support for anything that makes it even more obviously worthless. It’s been gamed by those with the skills and access since it first existed. The internet would be a better place without it.
The Whois database stuff is actually a decent point, and I’m working on some ways to automate RIR registration this weekend as chance has it.
From time to time I do indeed check where my blocks get advertised and utilized. One /22 right now is being used by a broadband ISP in Europe - and via nmap, traceroute, and BGP looking glass it appears to be legitimate, or at least quite well faked. The other blocks are colo and dedicated server providers competing with AWS/GCP/etc. Who knows what those customers are doing with them - probably a mix of good and bad like everything on the Internet. Functioning as-intended imo. If I'm helping reduce the need for CGNAT and helping a small company stand up to the giant tech conglomerates eating the world I'm calling it a job well done.

I'm sure that it's real nice to have the lack of IPs be a problem that only tangentially affect one's daily experience but try speaking to someone who lives in a jurisdiction that is de facto independent but because of a frozen conflict or some sort of political dispute that predates their birth can neither be assigned a TLD nor be a member of an RIR. There's a giant first mover advantage and the system devised to dish out IPv4 subnets is essentially a cartel. The secondary markets is the rational economic response in the face of a market that is monopolistic, poorly designed, and acts as an absolute gatekeeper to something that's fundamental to life in modern times.
The fact is that just because states and police really wish that 1 IP = 1 person but in reality that's hardly true. Residential and non-residential IPs are not really different. The resource is misallocated and what else does anyone expect? If investigations into actual criminal activity is solely based on IP addresses then it has always been one that is done incompetently. Sorry that the heuristic most convenient to the state isn't actually that great for what the state appropriated it to do. Whose fault is that? IP Geolocation is a massive backdoor whose purported efficacy has been used for geofencing warrants that basically make a mockery out of probable cause. It is also used for no good reason to help authoritarian nations and in the name of jingoism ends up inconveniencing people at the very least. My father spends 3-5 months out of the year in China and while there, he can't access his mortgage company and can't call them, can't renew his vehicle registration, can't check his gmail, and can't even purchase, but can nevertheless run, Turbotax. He's American, and there are hundreds of thousands of Americans overseas that find themselves in this awkward spot because of overreliance on one bad heuristic. So I have to pay his mortgage until he returns, every year for months, and also essentially while imitating him take care of a bunch of quotidian things that he can certainly do himself but since it's hard to teach a 65 year old man how to hop the GFW reliably, I have to go through this rigamarole. Imagine if I didn't have some cash set aside, or that I haven't paid for my own dwelling already. It certainly doesn't stop state actors from attacking when they want, but it sure makes it easy to pretend like you did something meaningful while in reality all you've done is inconvenienced your own customers. The system is broken, lamenting that fact isn't a good look.
The marketplace, in fact, is hardly a mess. It has competition, it has decentralized regulatory features, do you prefer all such deals go through say LET's massive thread on it instead? https://lowendtalk.com/discussion/160162/aio-ip-related-ipv4...
