We're probably close to the point for social networks where authenticity/transparency is more valuable than network effect.

You could probably have a workable social network just with the following properties:

1. Use combination of digital friend-of-a-friend invite chains as well as sign-ups at physical 3rd spaces to build out the social network

2. If a user's account is found to be abusing the network, kick the user that invited that account plus everyone in that branch of the invite tree

3. To re-enable an account from a kicked branch, each user has to visit one of your 3rd spaces (and temporarily lose their invite privileges after re-enabling).

4. Security engineers do what they normally do at social media companies, except you now incentivize them to publicize efforts to reveal attackers so that you generate foot traffic at the 3rd spaces.

Now instead of hiding a report that grandma is friends with a Russian bot, your giddy security team does a publicity stunt to kick 100,000 users on Thursday.

And that will generate record drink sales at your 3rd spaces on Friday. (Senior citizen's discount applies.)
