Yeah. It was virtually unknown on Lemmy up until around May 20th, when return2ozma and a few other accounts all started using it at the same time. It's sort of dropped off since then; I think their effort to make it catch on failed. But there are a few accounts that still like to drop it into conversation in perfectly natural fashion every now and again.
I think like a lot of propaganda, it's not meant to have any wild level of success on its own; it's more just one little piece that's designed to combine with a hundred other little pieces to create a sizable overall impact.
