Here's the complete First Ammendment:
Ammendment I: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
I found this on another site, but it applies all over the internet.
I have a right to free speech! What right do you have to delete my messages?
Yes, you may have a right to free speech, but not here. When you signed up for [this site], you voluntarily gave up the right to certain kinds of speech in return for the ability to use [this site]. If you do not feel that you can follow the rules here, you have the right to create your own [site] and make your own rules there. [This site] is a private business, and if you'd actually read the Bill of Rights, you'll see that "Freedom of Speech" applies to the government, not here.
