Should be the same place the Block button is.
That is assuming you didn't delete all the messages you had with this person. If you did then you have to send them a message first to have the unblock button reappear.
So the block / unblock function is dependent upon whether I save messages from a user.
Thanks - that solves my question!
PS: I delete all messages from users after a trade is done. I figure all those messages are saved in the swaps themselves so no reason to keep them in my Inbox/Outbox, especially if it's a trade that I canceled.
