Just checked out my albums that I have on there. I have some that have 0 views from June 2017 so they must have removed the delete after 6 months rule at some point. I will have to try from my Linux machine to see how much different it is. Maybe I can help out in some way.
One thing is, I only use Imgur for when I want to post images on a forum or Reddit. If people want a good option for backing up their photos online I use OneDrive. There are other options like Google Drive, Amazon, and probably a million others. If you use OneDrive or Google you can share the images from there also but last time I did that it wasn't very smooth.
