+			Notes of yours that you have favorited (aka bookmarked) or pinned will be excluded from this.

+			WARNING: Even if a note is favorited or pinned, if any notes above it in the thread are deleted (or autodeleted)
+			then the favorited/pinned post will be deleted as well. Consider favoriting all notes in a thread if you pin/favorite one of them.
