For those of you who've left the dark world of Twitter and have joined Bluesky (so far a much nicer platform) there are currently two accounts under the British Airways name. One (labelled as British Airways) is completely open that they're not the airline (possibly grabbed the name so that BA may consider paying for it), the other one (labelled british-airways) doesn't say anything but there have been no posts on the account so far. Best avoided for now to be safe.
