If social media bans people for abusive behavior, why is lawmaker Brian Sims still around?

Social media bans are a tricky business.

On the one hand, private companies have every right to watch their platforms for abusive and illegal behavior. But on the other hand, for groups such as Twitter and Facebook, which host millions of users, it seems like it would be impossible to enforce anti-abuse guidelines with any sort of consistency. Some harmful behavior is bound to slip through where it would normally be caught and rectified. This is the biggest problem for companies that claim to stand against all forms of “hate.”
