Sometimes it happens maelgwnau, unfortunately. Don't let it put you off reffing.
As Coby alluded to, the correct procedure for joshie is to go through his captain. Clarifications and questions should handled by PM or in the F7s mgt forum, not in the match thread.
We can only hope that Joshie will learn, although this is not the first time - he did a similar thing when I reffed a game.
