I blocked someone earlier and have changed my mind, but when I try to unblock them it says "Wait a while". How long should the wait be? I still have them showing as blocked.

I'm not 100% sure but I think it is 24 hours.

[edit] gonna move to Help forums since this is technically not a glitch. There's a cooldown to prevent block abuse, which does serve that purpose. Unfortunately sometimes it gets in the way like this too, like if you made a mistake. I've been there too so I know how annoying it is but unfortunately there is no choice but to wait it out :(

Ah, thank you. :)

some drama llamas were multiply blocking and unblocking stealth to cause problems and not to actually avoid contact which is what blocking is for. This is why there's a delay. There will also be a cache delay once it allows you to unblock.

sigh There always have to be people who ruin things for everyone. (But I guess if there weren't, there wouldn't be a need for a block function in the first place.)
