Hey, sorry for the trouble!
Here's the raw content of that post: https://browser.pub/https://greennuclear.online/@collectifission/117049521011751930 . Note that newlines count as characters. It's either 303 or 304 characters, depending on whether you keep or remove the trailing newline. (We remove it.)
@snarfed.org Ah, new lines, that explains it. Thanks!
