Behind a bar hangs a sign: "NO imitation intimation for intimidation!" What's? +...?

There are 7 signs total. The others have a similar message and have language labels aside them, yet they all are in plain English. Each has a key word (as in the 1st) and you can feel it out from there as to how the remainder might read. Find the keys and its fate as public is sealed. Can you? It won't be the end of the world if you don't, but it will be the end if you do, of ignorance of destructive aversion. I have 5, can't find 2.
