Banning people isn't violating free speech, don't be dense. I kicked some hunters off my property a couple weeks ago and told them not to return, is that violating their free speech?
Don't be ignorant, trespassing isn't in violation of speech.
I'm stating trolling doesn't hurt anyone.
Scammers do, but they don't get banned.
If you were to ban one for trolling, ban them all, and please start with dank.
Property doesn't only apply to physical property. You have no freedom of speech as it relates to other citizens and their private property. No forum can violate your freedom of speech because ...
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.
Who can't abridge the freedom of speech? That's right Congress can't. Last time I checked the mods on this forum aren't Congress, aren't duly elected or appointed officials of any state. They aren't even the agents of the state.
Rights start with ownership. The forum is OWNED by its owners. Those owners use admins and mods to (as they see fit) to maximize the value of their property. Property they own and have every right to control. There is no difference between kicking a hunter off your land and kicking a person off a forum. Both involve lawfully controlling one's property.
You don't need a freedom of Speech from other citizens you know why?
1) Other citizens don't have a monopoly on violence. Other citizens can't under the law use force to silence your speech.
2) Sure maybe you can't speak on this forum without rules (much like you can't hunt on anyone's private property without permission) but until bitcointalk.org becomes the sole mechanism of speech for the human race you have other options.
TL/DR:
I hate "rights" hypocrits. I bet even now you fail to see that your demands of freedom of speech are a violation of the rights of others ... the rights of property owners to be free in the ownership of what is theirs.
