I think he's referring to the supposedly unspoken rule that if you even so much as utter the word "Roblox" it summons demons or something.
In reality that's the stupidest thing ever. As long as your post doesn't resemble: "lolol sockland cigarettes ur game is wors than our game, ROBLOX is betr!" then no one but people who believe in this stupid rule will say anything about it.
Jesus, it's like if this were a Coke forum and suddenly everyone who even said "Pepsi", even if in the phrase of "I hate Pepsi", would get banned.
