Maybe? Maybe not? But if you’ve chosen to ignore them, then it’s up to you to tell them you’re willing to listen to them again. State your terms, plainly and fairly, and then they decide if they’re willing to abide by them. You don’t have to be public with it, a private message will do just fine, but you have to re-open communication with them if you’d previously closed it. If they could just contact you anyway regardless of the ignore, then the ignore might as well not exist.
You’re in control of your social circles. If you’re unwilling to let someone in, then don’t tease them or make them dance. Be mature and own the decision. It needn’t be final, but it does need to be yours.
I didn’t know this works that way but that’s cool, explains why I don’t see the same numbers as everyone else, shame they don’t just vanish completely though since I would prefer the people I ignore never see my posts and vice versa me with them like the other person doesn’t even exist.
Not to mention catching up in this thread the fact the super shady people think it’s okay to bypass ignores is exactly why account wide ignores should exist so that can’t happen at all anymore because no one should be able to continue trolling, harassing, sockpuppeting, etc. someone else if they’ve already annoyed them to the point they ended up thrown on ignore anyway.
