Exactly this. Of course, I do encourage people to call me if they need something or have questions. This way, they won't do stupid shit just because they're afraid to ask. That's also the reason they prefer to give me a call, because I don't scold them, like the other guy does.

But it can get annoying, if I have to tell them the same stuff over and over again. I do write information and updates about things in our intranet page. Including recent occurring spam mails, how to recognize them and how to deal with it. But apparently not everyone is reading that.
