This reminds me of how GPT-2/3/J came across
https://reddit.com/r/counting, wherein redditors repeatedly post incremental numbers to count to infinity. It considered their usernames, like SolidGoldMagikarp, such common strings on the Internet that, during tokenization, it treated them as top-level tokens of their own.

Vocabulary isn't infinite, and GPT-3 reportedly had only 50,257 distinct tokens in its vocabulary. It does make me wonder - it's certainly not a linear relationship, but given the number of inferences run every day on GPT-3 while it was the flagship model, the incremental electricity cost of these Redditors' niche hobby, vs. having allocated those slots in the vocabulary to actually common substrings in real-world text and thus reducing average input token count, might have been measurable.
It would be hilarious if the subtitle on OP's site, "IECC ChurnWare 0.3," became a token in GPT-5 :)
