Reply To: PLEASE BLOCK TWITTER
If you are using any of our paid plans, you can block it by going here: Settings->Custom Domains.
As far as our free Family Filter, we used to block it in the past, but many users asked us to remove the block since it is used by many schools and businesses. Tough choice on that one 🙁
I wish Twitter had a way for us to enforce Safe Mode, without fully blocking it.
