The Chofetz Chaim ztza”l was known not to be able to hear lashon hara, but was able to hear Divrei Torah.
But I suspect the problem HERE is NOT listening, most people type quietly (and most secretively), it’s the reading of it. And you’re most definitely right, I do try not to talk or ingest and lashon hara.
Oh, and by the way, the plunger job in my ears, was not such a good idea, I think…
