One of the few places of the internet that grant freedom of opinion and is not in the grip of the ads industry.
Anyone can create and moderate a board. There is for every taste, from totally safe to porn and shocking.
Unfiltered area of the internet. Visitors should be able to filter out junk and misinformation on their own before visiting. A last bastion of free speech, but be prepared for racism, sexism, and opinions you will disagree with. If you disagree with a board's general opinion on a topic, you will not receive a fair hearing. The solution should be to create your own board, and if you are unwilling to do that and maintain the board, don't bother. Some boards are regularly monitored by law enforcement (USA and others) to gather info on potential illegal activities. Use of a VPN is recommended.
