Why can't I have multi-media things in my signature?

I was trying to put a video of me doing the ALS ice bucket challenge in my signature, however when went to hit 'save changes' this message popped up.

I believe that only staff members have the ability to include multi-media videos etcetera in their signatures, please put in the comments below what you think

I wanted to put a video in my signature as well It's really annoying

 

personaly i think nobody should be allowed to, its annoying and spammy to me,

 

No one should, I'll talk to Cypriot whenever I can about it.

 

At the moment, only staff members can have multi-media content in their sigs. But I agree with everyone else in saying that nobody should.

 

My perms are screwed up and I can't put it in my sig anyways ._.

 

I honestly don't mind, just wanted to know
