Re: Imgur
"On April 19, 2023, Imgur changed their terms of service and announced that they would delete inactive content that was not tied to an account.
...
The new terms went into effect on May 15, 2023.[10] The move drew significant criticism, as removing archived images would compound the challenge of link rot that other photo services have also faced. The move also followed a similar move by Tumblr in late 2018.[11]"
I only vaguely remember this controversy.
