Not this forum but I have used something similar on another one.
For people who had the ability to rile me and the potential to bring out sharp responses from me, I would temporarily put them on the ignore equivalent. After that I would be aware that they had made a post but the content would be hidden from my eyes. However, curiosity always prompted me to override and I'd open the post anyway. It was then on me not to overreact.
These days, I'm much more placid and don't need to check myself in this way.
