Do mods ever delete signatures without telling users?

[IdeaOfEvil]

Yesterday I edited my signature in the CP, and today my entire signature is deleted. I see no messages or notifications about it being deleted, and I know when I edited it yesterday it showed up just fine. Is there maybe an automatic detection "something or other" that would delete a users signature on its own? Would a mod delete it and not tell you for some reason?

I'd just like to know what's up before I create my sig again. It only had four links - to my movie collection on DvdAF, to my digital code sale thread here on br.com, to my physical disc sale thread here on br.com, and to my movie review account on Letterbxd.

Thanks!
