Okay did some testing:

In the case of character name:

I try to initiate a social interaction with someone that is IGNORING ME:
If I try to duel, trade, group invite, or guild invite them - the invite either doesn't go through or I get an error result from the related event. So this is properly protected on the backend.

I try to initiate a social interaction with someone that I AM IGNORING:
If I try to duel, trade, group invite, or guild invite them - it CAN go through. If I do it by account name - it also CAN go through with account name unless a function somewhere in the way checks for IsIgnored(displayName) - so unless the PlayerToPlayer menu or Slash Command function checks - then you can still invite regardless.
By default, the player to player menu does gray out for any social interaction when a player is ignored. However, the /invite function still goes through (with characterName or displayName) & in the case of inviting someone from the guild menu it will only block you from sending an invite when you enter displayName, you can still invite ignored players by characterName.
