Flag content type "nilclass" — delete?

[bouteloua]

https://www.inaturalist.org/flags?utf8=✓&flagger_type=any&flagger_name=&flagger_user_id=&user_name=&user_id=&flaggable_type=Identification&flags[]=spam&reason_query=&resolved=no&resolver_name=&resolver_user_id=&commit=Filter&utf8=✓&flagger_user_id=&commit=Filter

Can these be deleted? Are there other content type=nilclass flags that should be deleted?

The recent update to flags seems to have fixed this issue.
