This is the wildest part. One company that is proving all the "why does <company> need 10000 engineers?" takes true.
For instance moderation and community management alone must be a huge pool of people. While the content and comments can be adult, they'll need to deal with all the payment related back and forth, including chargebacks, legal inquiries etc. Same for doxxing, underage filtering, spam and so on.
I assume most if not all of it is a different company which isn't counted in the 42 employees.
Of course engineering can be treated the same, with sub-contracting companies dealing with the actual running of the service or part of the developement.
