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/
Those services are seldom profitable. Especially as they get larger, their costs rise. Meanwhile, imgur, as a service that provides embedded content, has little opportunity to make money off of their users. They rely on infinite growth and ever more people investing money into them to keep financially viable.
But there is no infinite growth and imgur has reached its limits. Now they need to bind users to their platform and rely on ad revenue. So old content gets purged, along with nsfw content, in order to entice advertisers.
At least they aren’t putting ads into the images they serve… Yet.
yeah it does seem like websites are more affordable on smaller scale
The issue with that though is that they end up removing what made them popular to begin with, so then they lose their popularity and traffic and then they are worth nothing again lol
