They are still a tour master or below, but play like a legend.
The give away is they've joined about 3 or 4 months ago but play better than most of us who have been members for years!! (but if you are a natural talent i'm not getting at you just the cheats, who do this just for the $$
When you look at score history, they show many par rounds, (some even over par), but when you play them you notice they birdie every hole, and can sink long putts all the time.
They might even have loads of matchplay matches (this person had hundreds & hundreds, beating legends loads too)
You might be lucky and catch them out (like i did) slip in a line like, "did you make the cut for the open at oakmont then last year?" which they replied no, but i made the cut for St Andrews"......BINGO!!! How would he play last years open if account is only 3 months old? (A good tip would be to print screen at this point, especially if they've been bragging about their 2nd account and call us all mugs for being legends, this is the proof wgt uses) Usually when they've been found out they become very abusive, this too is handy for wgt because no one deserves abuse whilst playing and can lead to people being banned as well.
Feel free to add to the list..............
