I guess we will find out together, because my servers at HostUS just got listed on UCEPROTECT Level 3 as well. It feels like something perhaps changed yesterday and they decided to list a bunch of ISPs on UCEPROTECT Level 3. I suspect the listing impact will be very small. No big ISP will use level 3 for any filtering purposes. But some small hobbyists might use it. It would be unwise of them to do so, I think, but they likely will not value our opinion about it. There is a fine line between "granular reputation" to directly punish spammers or block spam without collateral damage and "block the whole ISP to get all their customers to revolt and leave." UCEPROTECT has always been somewhat zealous at driving collateral damage via level 2 and level 3 listings, in my opinion.
