Imgur now blocks several VPNs and have issues loading embedded previews in several fediverse platforms. So instead of using imgur, you could use one of the following alternatives for uploading your images.
https://postimages.org/
https://imgbox.com/
https://imgbb.com/
https://www.imagebam.com/
Which one of these alternatives delete the gps/exif data automatically on upload?
NOT postimages certainly ,that lights it up like a christmas tree (except ironically in the the preview I used to try to work out if it did)
For when someone answers this, @remindme@mstdn.social in 5 hours
I will have to test this manually across sites to know because none of them advertises themselves as doing this. But nevertheless, the best practice would be to strip down such data yourselves before uploading. There are many apps that will allow you to easily do that.
