I've found a malicious user who deleted varying amounts of songs from my collaborative playlists. Some of these playlists are works of art with around ~2500 songs in them, so I have a few questions:
1. Can someone from Spotify restore the songs that have been removed please?
2. Can I block the user in any way?
3. Can I report the user so that Spotify can send a warning?
4. Can I control who can make changes to the collaborative playlists?
