Running a public server requires more control over who may do how much on it.
Please provide a per-user quota for uploading things / auto-cleaning old stuff.
This is related to #718 as well as #733
Fixed in https://hg.prosody.im/prosody-modules/rev/2dec7cad9218
Will the quota be reduced if I delete old files on the server?
If a slot has been requested but no file has been uploaded yet, should it count towards the quota?
