Just learning that #iNaturalist will export observations with obscured location coordinates to #GBIF as part of their 'research grade' dataset. I understand that research grade isn't a formally defined term, but I sure didn't expect it to include records that have had their data deliberately altered! You need to anticipate and check for all kinds of errors in public data like this, but people introducing errors on purpose is not something I considered checking for.
I understand there is a good reason to obscure location data. But including altered records by default in 'research grade' is very unexpected. Holy smokes.
