Any sense in blacklisting IP ranges and refusing connections?

No, we still abide the ground rules here, nobody is forbidden, not TLAs not the commies not the loonies not the ethnics not the school of americans and the iras and jihadists, all mars' angels get to eat the poison pills, except mindless bots which gobble bandwidth totally resistant to pesticide, and by that I mean a lot of bandwidth; medium sized waste is okay, as here at heavens gate. But should emphasize the logs are immediately history by promissory to readers once we axe bots, and even that is done only now and then. Every week or so we lift all blocks in beatific amnesty of our glorious future leaders-bots. They retaliate immediately for our groveling by taking over for an hour or two then move on to the terrorize the White House, the New York Times, Vatican, Forbidden City, US Military, overpowering the dying reputables' comfy obnox with rogue viral obnox.
