I wanted more control over files I uploaded and shared and this is where pomf came in. I created a private fork, patched it and host it here at https://loaded.ie.
Files get uploaded at https://up.loaded.ie and afterwards are available to download from a seperate proxy at https://down.loaded.ie - super straightforward. Cloudflare handles DNS & CDN.
It's completely public facing, if you'd like to hook this up via Sharex or any other tool go for it. Nothing is publicly indexed, you need the URL to view the files.
If anything does need to be deleted for any reason, I've added an sha256 page so I can circle back and find/delete the offending material.
