Just FYI.....this actually happened to me. I belonged to this site back in 2009 and I had a R9, 275 yard driver, G10 irons and a decent putter.
I left for approx. 2 years and returned to the game. You see, when I left, there were no such thing as levels in the game. Also, you could buy the top equipment on the site at that time, even being a hack. I can't recall what level I was but I had killer equipment for my "level" when I returned. I did have a few people ask me how the heck I did it but after my explanation, they could see why.
I would have to assume that's the case you are seeing.
Here is a link of a friend of mine who did the same thing. He still very rarely plays but you will see what I'm saying. http://www.wgt.com/user/profile.aspx?UserID=935342
There are however level 90 hacks and pros running around the game. Take a long look at their stats before calling them cheaters / sandbaggers. Some of them don't care to play stroke and simply get on here to socialize in alt shot games.
