I wouldn’t underestimate it.

I used GBIF data in a project myself and I think people who use the data of specific species (especially when they are not so easily distinguishable) will usually check the records they use.
I honestly feel like I would trust other data a bit less then data that has photographic evidence. For example a lot of bird watch data is based on check lists people make and you have to trust that their data is accurate.
But I’m still new to the field so I might not see the whole picture.
