If the ignore button only prevents YOU from reading the material no-one could reasonably object to that. I thought it was a general censorship button that would prevent anyone from viewing the material if posted on your art work. Am I wrong?

On balance I value free speech more than the ability to remain unchallenged. I've had abusive people on Deviant Art but I find them easy to deal with because abuse carries no argument and I figure that anyone reading the thread would realise that. On the other hand I once commented on a picture by a commercial texture artist. It said nothing derogatory about her work or anything abusive but had the afront to list my opinions of the very best textures available. She got a mention but not right at the top. So she reposted her work and claimed that someone had been really rude to her which was totally untrue. Presumably my crime was not to fit in with her notion that she was the very best texture producer there was. Whats to stop people like that claiming you are being deliberatively disruptive? No share all views and let the reader decide who is being reasonable.
