A hash of the (say) /24 part of their address (and/or the IPv6 equivalent) would probably be a decent compromise being fuzzy enough to reasonably smear things likely from the same source. I'd be most surprised if there were someone commenting from the same block as the infamous one. If the hash were stable and made it into the CSS somehow as an attribute or class that would be even nicer.

    I ran an ISP as the senior global network engineer for a decade, and I am against blocking based on IP block or in most cases address level. I've always believed that any risk of collateral damage is too much risk.

    IPs can be spoofed (although that's admittedly become much harder in today's age), people forget to remove the restriction, admins can mistype the prefix and wipe out an address space way larger than they intended (yep, I've done that one... blocked most of Australia once by blackholing way too large a block, and took me a while to sort out WTF because the problem didn't crop up for a few days after the change).

      Oh no I didn't mean block as in block the IPs, but as in hash every IP in the same /24 net block to one identifier so that e.g. someone bouncing their cable modem probably would still hash to the same token.

        Not reliably. For example, the Deutsche Telekom owns several pools of IP-ranges, and randomly assigns an address from a random IP range when reconnecting. (Their internal routing must be interesting ...)
