@gpfjeff By "site", you mean the comment system?
Have you looked at pubkey based comment systems? Spam drives account based interaction toward centralization - via the mechanism you are experiencing.
Here is a comment system based on the Nostr protocol (low barrier to entry for newbies):

@customdesigned Sorry for the late reply. While that link looks interesting, I really think very few of my readers are going to go through the trouble of generating key pairs for authentication to a comment system on any site, let alone mine. (Sure, I have a geekier audience, but that's a lot of hoops to jump through to say, "You misspelled a word in the second panel".) My current spam-blocking strategy works well enough. I'm mostly venting...
@gpfjeff You need a friend to relay mail. I do that for customers that get on ban lists for similar reasons. (And silly reasons, like forwarding all their mail to gmail for "spam checking", flagging spam on gmail and wondering why gmail then bans their MX...)
I'm sure you already have friends that run an MX. But if not, you can relay through mine. I haven't met you personally, but read your comic.
