I used Power Delete Suite (javascript IIRC, via Firefox, year ago) to edit and delete, and mine are still gone. Not sure if it is still effective.
Reddit is probably less and less tolerant about edits and deletions, now that they’re full speed on selling our data. Still see plenty of deleted posts when I’m searching for things, which is… nice I guess (bittersweet).
I think this is what motivates me to play AC games the most: They really integrate accurate locations and history into their story (with plenty to read and learn about in menus, and even tour modes). I was especially impressed with Origins (Egypt) and Unity (France). Haven’t had time to play newer ones yet.
