How? Why?

Hey everyone! I was logging on AJ to get the Jamaaliday gift because I wouldn't have time the rest of the day and AJHQ gave me a surprise:

It got me a little worried because this is the first time I got suspended. Is it because I gave Cerise my email on AJ to make me an author of TPC? Is it an other reason? How long will I be suspened? I also wonder if I should tell AJHQ. The thing is, I've never told them my username for some reason. I just put my gmail name, Shiver Snowybell. If you think I should ask them, say so in the comments! For now, I will be on my storage I guess.
