There are forums that promote suicide and self-harm, where people can post revenge porn, AI porn etc. They have been able to exist because those sites argue that they can't be held responsible for what their users post as that the try to "moderate" their site and "remove harmful content", when in reality they do nothing.Nonsense. People are in prison for Facebook and twitter posts.
They are as open to legalities as any other digital communications.
Twitter is irrelevant to THIS forum being forced to shut down parts to satisfy this need to control discussions.
THAT is the issue.
This law isn't shutting down discussion. It's making those discussions the responsibility of the site owner who is hosting it. I have no problem with that, but do feel for sites like this that haven't got the bandwidth/finances to manage it.
