@Em0nM4stodon Thank you for this PSA! I saw the fallout from this event and it's truly a sad case of mismanaged expectations.
Since I do bridge both my Mastodon accounts I'm trying to figure out how to handle this now. I guess ideally I'd only want posts of mine that do not reference other Mastodon users to get bridged, possibly with the addition that posts mentioning others would be bridged if (and only if) those users themselves are using the bridge.
I do believe a technical solution will [also] be needed since it's going to be impossible for everyone to remember to ask before tagging someone in a post.
