Came here to make the same comment. I love the videos and watch every one of them. I also switched to Knots…even before this op_return nonsense. However, if the transaction is confirmed, your Knots node is going to download and store it whether you chose to relay it or not.

With regard to the ‘attack’, is there some sort of legal distinction between ‘transmitting’ and ‘storing’ this horrific data @Matthew Kratter ?
