As someone familiar with Spike's posts I think she has a tendency towards hyperbole at times. I can't really say with certainty she literally believes in that number. But as i stated before she probably muted the thread with all the bad faith folx and I'm not close enough to ask her with an @ or DM.

She’s blocked me so I can’t even see it anymore but I will say I’ve heard bad things about her from others. Some shit about her apparently writing a manifesto for homophobic furries or something like that. “Burned furs” is the term I typically see used to refer to this.
