By continuing to allow Donald Trump to use your service as his platform, you are approving of and facilitating his messages of hate, isolationism, xenophobia, racism, sexism, and bigotry.

He is doing great and and irreversible harm to the world with your help.

You are not a government. You are a business. By allowing him to use your service, you are helping him for your own profit. There are times when right and wrong should matter more than profit, and now is one of those times. Ban his account like you would to any other hatemonger.

The money you make by letting him promote himself through your service is dirty. We are asking you to say no to it.
