You have to worry about using Mixer when you are using centralised platforms like exchange and wallet services. Binance is already spotting transactions related to mixers and asking to provide a source of funds. You may definitely face this kind of issue when using the mixing service. The forum didn't prevent you from discussing related mixers, but don't advise with mixer links or don't hint to use mixers. I think you have to find alternatives when you want to protect your privacy and hide your funds. We have to use swaps or decentralised exchanges to protect privacy. I feel it is better to avoid mixers since they are facing a lot of legal issues lately. Law enforcement agencies consider money laundering whoever uses mixers. So you would be one of them if law enforcement could detect you.
