Could everyone who has lost regular badge get it back?

Soo @Dev half and more forumers have lost their regular badge, could they get it back or rules have changed?

i still have it
the worse thing i cannot edit title

Well, yeah, it’s a badge so…

I’ve lost my autobiographer badge once, when I tried erasing my profile information but got it back when I filled it in again, so it would probably be the same as regaining the regular badge, you just need to get trust level 3 all over again.
