my recent experience testing that coarse ID app another user created definitely hammers it home - it was fun to do, but i got tons and tons of notifications and saw that often the original poster just hadn’t put the ID in yet. The tons of notifications speak more to the issues with notifications (which are being upgraded soon anyway) than anything else, but even still it felt counterproductive to jump in and add IDs when they were about to be added anyway. I agree it may be a bit different with new users but even still waiting a day or so seems more helpful. Many of them don’t even use the website, just the app.
And again, as cassi said, you aren’t doing anything wrong with adding coarse IDs. it’s true that without a way to add draft observations they can be a mild annoyance for high volume users, especially when a placeholder gets lost. But… that’s just how the site is. There’s no way of excluding individuals from that sort of ID other than just manually. You can filter to ignore someone but, no one can be expected to do that as a matter of course.
