@sunguramy Yes, still considering what to do about it. A fix *has* been rolled out so many instances will be fine going forward (e.g. those on managed hosts where instances are upgraded en masse), but it obviously doesn't change what may have been accessed in the past. There also isn't a quick way for me to see which Pixelfed instances we federate with—I could script something but it would take me a little while to figure it out. It would also take some time to use that to generate lists of users on those instances people here follow/are followed by.
I have had a long day and don't have the wherewithal to do much now, but will be able to look into it more fully tomorrow.
