A 'friend' of mine has found a way to bypass the nudge thing so now he can just continuously nudges me when i'm busy. Is there anyway (other than blocking him) that I can do the same, just to give him a taste of his own medicine? Any help is appreciated.

This question has been asked before. Take a look at Nudges??? and/or anyway to nudge unlimited? for example

Thanks, got it sorted now, that'll teach him
