Mitch the Christmas Angel is Back?!?

Okay this really weird thing happened to me... Yesterday I had 362 friends on Splashface. Today I have 363 BUT I did NOT accept anyone new!!! So, I went through my friends list and saw that the only NEW person on there was Mitch the Christmas Elf. Or wait... Christmas ANGEL. (I always get that one confused.) Elf or angel, whatever he is, I know I NEVER accepted him.
This is so strange. It's totally freaking me out! Can angels just become your friends without you confirming that they are indeed your friend?!? If so, I don't think that's fair. And, btw, how does he even have a Splashface account? Is he even real? I thought that whole Christmas thing was just a dream. Ugh. Do you think it's bad karma to de-friend an ANGEL???
