When you block someone on Splitwise, that person is automatically removed from your list of friends and balances. Additionally, the following kinds of information are also hidden:
-Any groups that involve the blocked person
-Any future notifications from that person
-Any future "recent activity" entries caused by that person's actions
Blocking another person does not notify that person about the block in any way.
