I was wondering, because I know how I am. How do others feel when you're on a site, and see a private message, from one of the top dogs? Personally I assume the worst. Today I signed on to Iwaku, noticed I had a PM from some Moderator, whom I had never contacted, had no reason to get any contact from them, and my thoughts were pretty much;
"Okay I'm probably in trouble for something."
So I deleted my account. There's a lot more to it than just that. I was already on the verge of deleting my account, due to harassment, but that kind of sealed it.
When that happens to me I just check it out. If I'm in trouble then so be it, but just remember that they don't know where you live or anything like that. If you get in trouble, all they can do is delete your account or ban you from the site. They aren't going to come to your house or send a note to your parents saying that you're not allowed to come onto the website ever again.
