It appears as though Community has an answer on our meta: Do we really want LaTeX/MathJax (right now)?. I've checked a few other metas on the network, and I can't find any other instance of Community posting answers, aside from some automated stuff.
Additionally, Community appears to also go by the name anon in the revision history of this answer.
This appears to be very weird behaviour by Community, as I'm unable to find any other examples in a brief search of other sites, and it doesn't appear to be any of the listed behaviours for Community
What's going on here?
