Can you provide a use case for having this information? The only one I can think of is if you suggest a user ignore another user and want to follow up on it but that is not information I need myself. But I am curious to hear your use case.
In this case I would not need to know who is ignoring but only who is being ignored. That is not a bad stat to have, but I am glad you found the solution. If I ever need both, now I know.
