# of users is almost impossible to count - you have to start with the definition of a user: is it someone who joined or someone who posts? how much do they need to post, and when does their latest post need to be to count? Are 10 accounts by the same person 10 accounts or 1 account?
I'm sure we don't have as many users as Reddit, it's a much larger platform, although a lot of user-counts on large platforms are fake and inflated as part of their business model with bots etc... for spam too. It's also a tribalistic cesspit of corruption that's been taken over by leftist fanatics.
