So startrek.website have cleaned out their spam bots. Looking at the graph of their user counts on #fedidb gives a sense of the time course of the #lemmy spam bot problem.
If you presume the same time course for lemmy as a whole (which fits, see here: https://fedidb.org/current-events/threadiverse), lemmy’s true user count is somewhere between its June 18 and 19 numbers … ~200k, somewhere around Pixelfed/peertube territory.
Bigger instances might grow faster.
