I understand why ignoring cannot be automatically mutual, it would create quite a mess.

But I would be happy if those I ignored could not PM me and I would be happy if I got an indication I cannot PM them if they have me on ignore, I mean if someone would choose to ignore me, the least I would want to is private message them, it would probably feel creepy for them and I would be clueless.

Also it would be great if one could make the profile invisible for ignored people. I know some people I put on ignore actually commented on my profile (I peeked I admit and realized it's quite scary when you cannot see them and they can still see you), commented in ways I found quite disturbing. My profile is now very generic and I feel the need to make it moreso. I mean, you have to protect yourself, right?
