In the future I could also add a subscription account for additional features, access to an API, bigger upload limits, transformations, greater ability to organise, etc.
As a sidenote, reddit is (was?) the one of main user of imgur, however https://www.google.com/search?q=%22haasie.com%22+site%3Aredd... yields no results - maybe it is worth to promote it there also.
One is to turn off any new uploads, and just serve the existing content, presumably the bandwidth on old content would be much lower - until some sustainable plan can be devised.
Last resort is to approach the ArchiveTeam mentioned here to see if and we could to setup a maintenance service.
To your side note, yes, I want to promote it on Reddit, as soon as I've added a few more features - like donations.
