"Has everyone's sales directly decreased by 90% since April?"

NO, not that much. Mine are 'kind of' holding their own at this point.

"Does this have any impact on recent events?"

No, no one in charge of anything asked me how my sales are.

NOW, do you mean are sellers being affected by recent events, then that is a different question.

YES. Boycotts, tariffs, stock market tanking, marches in the streets, deportations run amok. ALL of those external forces will have an effect on sellers here (and every other site!)

Buckle up and wear protective gear. It's going to get rough out there.
