Okay, but I’m just the lowest of users, who snuck in here trying to get you to guys to change some worldwide defaults (skipping the middleman (site admins)).
Anyway, I still say that not allowing people to unlike something (even after a year) is unlike anything I’ve ever heard. Would Facebook ever dream of that? So I’m thinking you should just rip that right out of the hardware… I mean software. So no admin could even get their hands on it.
