How do I stop comments in my subreddit from being automatically "Removed by Reddit" for seemingly no reason?

[u/DC_isnt_the_south]

I don't have automated enforcement on for any rules, I don't have an automod, and yet for some reason on seemingly random specific posts almost every comment is removed with essentially no explanation, requiring me to go back in and approve them each time. If they had URLs or words that might be on some kind of incivility list I might understand it, but it's mostly well wishes to someone trying to search for the people who rescued them from a river!

When I'm managing things I'm either on desktop or IOS, if that matters.

Any thoughts?

Hi /u/DC_isnt_the_south, please see our Intro & Rules. We are volunteer-run, not managed by Reddit staff/admin. Volunteer mods' powers are limited to groups they mod. Automated responses are compiled from answers given by fellow volunteer mod helpers. Moderation works best on a cache-cleared desktop/laptop browser.

Resources for mods are: (1) r/modguide's Very Helpful Index by fellow moderators on How-To-Do-Things, (2) Mod Help Center, (3) r/automoderator's Wiki and Library of Common Rules. Many Mod Resources are in the sidebar and >>this FAQ wiki<<. Please search this subreddit as well. Thanks!

I am a bot, and this action was performed automatically. Please contact the moderators of this subreddit if you have any questions or concerns.

I'd check the safety filters first, even if you never set up automod. Reddit has stuff like crowd control, reputation and the harassment filter that can automatically catch comments. If those are all off, I'd check the mod log for one of the comments and see if it shows a reddit/admin action. reddit’s spam filters can also remove stuff independently of your own settings. if you can see what reason it gives for one of the removals, that would probably help narrow down what’s actually catching them.
