How are people suppose to know you have them on ignore?
What you’re describing is very specific in context of what you’re asking for and they would likely get flagged down and suspended anyway, as everyone else can see what they’re posting and suspensions are account wide.
That’s the nice thing about unified accounts. You don’t have to worry about that. Or about which character has your TL on etc. Just simplifies things nicely.
This isn’t a question of functionality, its a question of establishing intent.
Not everyone who alternate between alts is automatically guilty of trolling because a user has come to the conclusion that they’re doing so just to circumvent an ignore they’ve place on another poster.
She’s not careful about what she says and gives out too much information. Not gonna call out her toons, but I do know quite a bit about them, just having them on ignore is good enough for me, forums and ingame,
People who have ignored me for say my participation in the great pretty pixel elves war don’t effect what I can do on the forums, and it doesn’t hurt me that they wouldn’t see what I typed if I swapped characters for a joke or something.
You just don’t present a single iota of anything approaching showing that your hypothetical scenarios would actually cause a problem, much less actual be possible.
