If you're using a script to do so, make sure it's handling API limits specifically for "edit" calls. I realized after I tried overwriting mine that it was quietly skipping a bunch of comments, presumably because there is (allegedly) a 1 edit call per 5 second rate limit. Since adding a 5 second delay between each re-write, it seems to be working for me.
I ran into this issue with u/j0be's Power Delete Suite, I ended up writing my own script to do the job.
This is what I did. I also added some stats about the account: account age, total karma, # of comments, ect. Otherwise it's not clear how much value is being lost if you just come across the comment in the wild.
So what's the best edit we can go for? Dunno if FU u/spez is great. Shouting out the fediverse? What's the go-to edit users are going for?
I think something like
"Comment removed in protest of Reddit's API policy"
is best because if non-Redditors stumble across it it might dissuade them from joining Reddit. It is also very clear as to why you are unhappy.
