How does Ignore work?

[Vrakthris]

Does the Ignore function operate across factions? So if I play with a character on Horde that I want to Ignore, if I then go onto an Alliance character and type in that same Horde character, will it have the same effect as if I’d put in an Alliance character?

It should, yes.

What are the situations where the Ignore works? I recognise it blocks communication, but does it block all dungeons runs, all raid runs, all LFR, all premades, etc? That is, is it still possible to have that character with me in any game content?

It should block communication and the LFR/LFD systems will avoid grouping you with anyone you have ignored. That does not work for group finder since that is just a tool to help you find a group, not something put together by our system.

They will still be in the world, you may not be able to see their chat or otherwise interact with them, but they don’t disappear from the same areas you can go to.

Is there any way at all (apart from some form of add on) to block that player’s characters across my entire account? If not, is there any consideration being given to institute that option? I ask as I find it very tedious to have to do it on all the alts manually. If I wish to put a player on Ignore, I want the player ignored, not the characters.

No, and likely I’m afraid Customer Support isn’t privy to what design considerations may be discussed. Since an option is in place that does the same thing, though requires you to manually ignore the character on other characters you wish to also ignore them on.

If you’d like to see it function differently I’d recommend using the Submit a Suggestion option located in the help menu so our Devs can see it.
