Back when I first joined Inat in 2020 I would “speed-ID” where I would just click Agree to everything RG and adding supporting ID’s. I only did this for less than 2 months however to this day I still get messages and tags for species that I have zero clue about.
yayemaster’s 2020 iNaturalist Year in Review · iNaturalist You can see the spike here in June/July.
To this day, I am still the top identifier of Harris’s Hawk, American Pygmy Kingfisher, Razorbill, and many other bird species that I identified from the Ebird randomizer.
Is there any way where I can be excluded from the leaderboard for these species since I am not familiar with them? I don’t want new users to think that I am an expert in these taxa when these IDs were 99.8% supporting RG observations.
No, there isn’t a way to do this without removing your identifications.
One option for your scenario is to go back and withdraw or remove those IDs.
Is there a fast way to do this? I am getting an “I ate Inaturalist” whale when I try to go to the back end of my identifications.
Don’t panick 
I totally understand your concern over other users falsely believing you to be an expert identifier of these species that you added uninformed supporting IDs to, and I have probably done the same. You know what though? It’s not that big of an issue, plus the time that you would spend withdrawing those IDs would be better spent adding informed IDs to Needs ID observations. If someone tags you asking “What hawk is this?”, be honest and reply “I don’t know”. Normally birds are identified quickly anyway, so you shouldn’t get too many tags, and others will surpass you in the leaderboard eventually.
Within the iNat user interface I’m not sure what is fastest but sorting by observations least recently updated will help you find your old IDs: https://www.inaturalist.org/observations/identify?reviewed=any&quality_grade=needs_id%2Cresearch%2Ccasual&order_by=observed_on&order=asc&ident_user_id=yayemaster&taxon_id=5355
This view will jump down the page to your ID which would be faster: https://jumear.github.io/stirfry/iNatAPIv1_identifications?user_id=yayemaster&taxon_id=5355&order=asc (if you click the ID #, not the obs #/)
You could work thru your IDs for those first.
And leave a few lines on your profile ‘don’t ask, IDK’ …
Thanks!
Here is another possible solution: learn to identify those birds for real. Become the expert people think you are.
Now that’s the real solution! Never thought of this!
