I don't know the stats but @yabapmatt told us today what many of us suspected. It's hundreds of thousands of accounts that are currently bot accounts.

There's only about 350k daily active accounts and we know the bot accounts don't miss a day which means most accounts are bots right now. I'm guessing its 2/3 to 3/4 of all actives now are bots but I have no way to know for sure.

If we see a sudden large influx of new spellbooks sold theres a pretty good chance we're getting bot invasion part two.
