“Monthly Active Users” I think.

Made Up Users, apparently

This is how reddit started.

If there are already articles proclaiming that user traffic is back to normal, I’d be surprised if this wasn’t already the case at Reddit. Lots of subs I’ve been at have had wonky traffic and subscriptions behavior that looked like bots.

Reddit sells ads. They do this by convincing advertisers that access to their traffic is worth money. They’d be crazy not to cheat their metics, if it’s possible to do so.
