I'm not sure how many years you have been bridging in but with recent developments like Matrix logging all chats (including a second bot after the first one was banned) it sounds like too little too late.
It seems this caused concern because archive.matrix.org didn't have UI to explain why a given channel was visible (i.e. "chanop Bob explicitly set this channel to be world-readable on the Matrix bridge on Jan 1 2017") - and so after we got complaints from ircops last weekend we immediately took the service down to double-check and add the UI to spell out what's going on (and give the IRC channels & networks in question a chance to mark themselves as non-world-readable if that's what they want).
As I said, we're trying to be good neighbours, but there's a lot of ill will flying around.
