No, the only way is to look at threads from another account, or when not logged in (but won't see everything) and then see if you can see the posts that when you're logged in you can't.So there is no way to find out whose ignore list you might be on?
You'll know who she is but I won't say however I can confirm you aren't ignoring her as she can see you!If we knew who Mrs Shrekfeet was we may be able to check she's not on ignore.
