I setup a temporary instance of morning-glory running on a LNVPS I forgot I bought a few months ago https://vm-217.lnvps.cloud/ It costs 1sat per kB for uploads and all blobs are deleted after 24 hours... Not sure if its any use to you guys but go ahead and try to break it. I don't remember how much storage the VM has so it will probably fill up fast github repo:
