Almost! At the time of this post, lemmy.world has a whopping 25733 users and is growing fast.
Since my last post yesterday, it has added 4000 new users, making it the clear second-largest lemmy instance out there. Also quickly catching up to lemmy.ml's 36000 (not taking new signups).
beehaw.org (3rd largest) sits at 12500 users, partly because of more restrictive registration requirements.

Exciting to see all this growth!
We do need better tools don't get me wrong! That said... Admining for some bigger communities I have had a total of 3 reports, only needed to act on 1. Banned 1 person, from a small asexual community I run for bigotry but outside of that... It has been pretty quiet. Not to down play it beehaw probably deal with a lot of shitty people too. Especially in the bigger LGBT+ community.
There are some really toxic instances out there, but as far as they go. I don't think Lemmy.World is anything worse than what you see in Reddit on a good day.
