I plea guilty though you won't ever notice it - usually I exclude Hacks (and sometimes Amateurs) from my matches from the very beginning...
This is not a Master's arrogance but most of the time I like to play competitively, not willing to see a rookie hack his way around the course or have to accept him as a partner or opponent in an AS game.
So, why should my free will to accept or to deny players for games be constrained? Should I be a part-time slave of WGT? No, this ain't the right way. When I'm in the mood, I'll enter a practice game and I'll be glad to share my knowledge...
Having said this, i'd like to encourage you to accept my friend invitation and share a round or two.
Furtheron, your avg is too good for a hack - it's an Amateur's avg. Thus, knowingly or not, you appear like a sandbagger and many players react allergic on such thoughts. I've seen in your game history that it comes from but two fairly good ranked rounds. You need less than a handful more of this kind to become an Amateur, creating a better acceptance in the player's pool.
Nothing is wrong, enjoy your game!
