Jammer Wall Hacker(?)

This is not exactly a creepypasta. But it is something creepy that just happened to me.

I don't know if you know but AJHQ had a new update for a Jammer Wall. Yup, the rumors were true. Right now it's being tested by members only. I went to my Jammer Wall and typed in, "Hello." no answer. Everyone was saying their walls were glitching. My friend couldn't get in my wall. I set to option to "Everyone" so anyone could enter my Jammer Wall. I asked buddies to join but they said my wall was unavailable. I then went to Aldan to trade and forgot about the wall. Then an hour later, I went on my Jammer Wall and there was one message. The message said, "cupcakes are delish." I wondered how the person got on my Jammer Wall since it worked for no one else. I clicked on the person and it said, "cupcakesaredelish." But the weird part is, THE PERSON WAS A NON MEMBER. The Jammer Wall was currently for MEMBERS ONLY. I then deleted the message a bit frightened. I then searched up the person, "cupcakesaredelish" again. But only this time it said, "That jammer couldn't be found!" I then reset my Jammer Wall to buddies only. If anything else creepy happens to my Jammer Wall... I'll post it here.
