I want to do some cleaning up on my !gnusocial instance and have a few questions:

1. Say I just delete everything in the avatars folder; is there any way to get those avatars to redownload?

2. Does the file and thumb folder (within the files folder) only contain attachment screenshots (like attached photos and video/link thumbnails)?

3. Can you clean the file and thumb folder in a "proper" way? My instance is small and those two folders take up over 1G of space with *many* pictures of varying sizes. Using the following scripts don't seem to help: https://wiki.realmofespionage.xyz/servers:nginx:gnu_social#service1

4. Is there a clean way to remove Qvitter? I figured I could just disable the plugin and remove the folder, but I noticed some errors about URLs not being found pointing to the Qvitter folder still.

5. Say I redo my instance from scratch and keep the same profile name and URL; how will other instances treat this? Will my status updates still federate?
