Why am I getting reply notifications from people I have on ignore?

This has happened quite a bit over the past few months.

The forum won’t tell me WHO is replying to me, but it tells me I have a reply and clicking it brings me to the ignored message.

But it does it with regular replies too so I click to be brought to the reply every time.

I have them on ignore for a reason. I don’t even want to know they’re posting.
