There are a lot of ideas I have to help solve these issues, but one has to be careful not to sacrifice privacy or other core principles when dealing with this.

I could write a more automated system using trained models to identify this, but in doing so, we'd need to ingest and store so much user and meta data.

And in doing that, we could get too comfortable in collecting and using that amount of data that we'd be no better than Instagram.

No easy way to solve, requires careful consideration!
