For what it's worth, here's the average position over time for our homepage for "flat earth society" since September 2020 (the new version of the search console only goes that far back).
Looks like we had a collossal dip over the summer, but we're currently roughly where it always were. It may be that your personal search results are affected, but the average doesn't seem to be.
Data for "the flat earth society" is very spotty, since very few people choose to include the "the" in their searches. It only gets about 10-20 searches a day, so it's subject to much more variance.
