@mxmehl I know. Unfortunately that's not something I have included in the table (yet) :/
Until then the best option is probably to ask on the peertube hashtag like you did, and reach out to admins of instances with matching criteria in the meantime.
Note that admins can override quota on a per-user basis. So asking nicely can get you more quota. It's even a common thing to see instance admins put a low quota and explicitly ask their users in the terms of usage to reach out for more. It prevents blatant spam and at least establishes a link with the admin.
Note that the HTTP import feature can be disabled/enabled by an instance admin, but it will only affect the web interface, not scripts that do the import on your computer before doing a regular upload (like the peertube remote tools do: https://docs.joinpeertube.org/lang/en/docs/cli/add.html).
Good luck on your search for a new (video) home!
