Magic Forums

So, I was talking with someone on the mail system and It said that the person blocked me, so I thought it was just that the person didn't like me and moved on. But after a few minutes the person mailed me saying that it said that I blocked them too, I couldn't respond because it still said they blocked me. So what do you think happened, did the person block me? or is this a glitch, and if so should I go too Petrarca?
