Is it still against the rules to talk about other games?

I was wanting to talk to some people about this game I used to play called Graal. But I don’t want to get banned. The game doesn’t even exist anymore but I’m afraid to even say the name of it because someone might report me. Could I get banned just for saying “Graal” or any game for that matter? If it only pertains to advertising, I’m still not going to say the name of the game at all out of fear of confusion

I come from 2005 where we would get banned for saying poop :/ just scared Thanks
