I've never found practice PAN calls a problem when I'm listening out on 121.5- I do tend to turn box 2 off when I get back into busy airspace, so the risks of distraction are reduced. Usually, when I hear some other extraneous call on Guard, I think "Glad that wasn't me!" then get on with what I was doing.
Occasionally I will transmit "you're on guard"- but only when I have heard the same call twice, and it is obviously someone on the wrong box- even then I am only trying to spare them embarassment!
However, I have also heard some exchanges of swearing on Guard- given that autotriangulation is possible, is it time that the perpetrators are identified, and MOR action is taken? We all make mistakes on the RT, but deliberate abuse is quite another thing...
