+  This migration creates a MUTED relationship between two edges(:User) that have a pre-existing BLOCKED relationship.
+  It also sets the createdAt date for the BLOCKED relationship to the datetime the migration was run. This became 
+  necessary after we redefined what it means to block someone, and what it means to mute them. Muting is about filtering
+  another user's content, whereas blocking means preventing that user from interacting with you/your contributions.
+  A blocked user will still be able to see your contributions, but will not be able to interact with them and vice versa.
