It’s pretty annoying to read the mailing list, I agree. There’s a very small hyperlink that says “next” that’s right below the message body. If you click that, you can read the next message in the chain. Keep doing that until you get to the end, and yeah, it looks like this was resolved and wasn’t actually malicious.

88 can absolutely be a fascist dog whistle. (It may or may not be here, hard to tell.)
Here’s the explanation of they dog whistle: the phrase “Heil Hitler” becomes just the pair of letters “HH”, which then becomes “88” since H is the 8th letter of the alphabet.
88 by itself is kind of rare, you’ll usually see it paired with 14, most often as 1488. The number 14 is a reference to the 14 words which is a fascist saying that I can never remember but can always recognize. To paraphrase, it’s something about securing the future for white children. It’s pretty easy to find if you just search “14 words”
