It's probably a bot account that tried to read the article to come up with a reasonable comment, but TCRF likely serves a "you're a bot, go away" static response page when it's accessed by bots. Pretty funny.
I take that back! It seems to be happening to multiple people using VPNs. My bad. I should have been more charitable.
Funnily I think you are still right re. the specific account under discussion.
There do seem to be annoying false positives, but this particular account really is a bit strange. Months of silence after signing up, and then this non sequitur…
The style is also very LLM-y, though not a complete slam dunk.
