Some problems are not solvable in software. They are emergent human behavioral issues that are not obvious until larger scales are reached. When you reach scale you have issues with threat actors at different levels. One is the platform operator itself, scale costs money to run and exploiting human weakness is one way to pay for the operation. Others would be scammers/spammers in a system. Then you have the users in the system that can be threats to each other.
There is no easy time for anyone to provide solutions to these problems and it's possible there are not solutions at particular larger scales.
