Thank you!
My thinking is to start with donations. There is no such thing as a free service. If people get value from using it to upload anonymously and they want to keep it going, makes sense to donate.
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.
Is there a backup plan? Not saying that relying on donations is impossible, but realistically there is a very small chance that enough donation will flow in continuously.
Your question honestly got me thinking. If everything goes completely sideways there are a number of shuttering options I can think of.
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.
