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.
Yup, I could see Reddit noticing a large number of comment edits and bumping that timeout higher.
Also, many users probably don’t know what forks are and might just run the first version of PDS they see, see that it isn’t “working”, and give up or wait for an update that never comes. The userscript is easier to understand because it visually performs the same actions a person would take to edit comments. And it’s more fun to watch than PDS’s progress bar. :)
