Made a comment, edited said comment, came back and I swear my comment was subtly different than what I had written. It showed that the comment had been edited 3 times -- I might have done it twice. I've since deleted said comment, but I'm wondering who, if anyone, has the ability to edit my comments.
Yes. ♦ moderators and devs can edit anyone's comments. Typically, this is only exercised just to do minor spelling fixes, remove dangerous content, or at request as per some flags.
We are also not limited as to how long of a window we can edit anyone's comments, but editing any comment other than our own is in fact tracked.
