There are many tags which are blacklisted. And so are some strings/words/phrases in the title.

Is it possible to have a list of them publicly available somewhere?

As I was told by a moderator in chat: "Some of the blacklisted input is more sensitive (some stuff that helps prevent certain types of spam). Blacklisted items that we've requested are probably safe to state publicly."

So could we have at least list of those which are safe to publish?

Blacklisted tags

I will start here list of blacklisted tags based on past discussions and information I was given by Arthur Fischer in chat. I made the post CW - it should be expanded if some new tags are blacklisted and if some other information can be added.

Other blacklisted input
