"Last year there were at least six such DQs."

In the July 25th Golf World, Ron Sirak pens "The View" titled "Defending the Rules" (not posted online). In it he notes this item related to the Michelle Wie scorecard signing incident:

In truth, the LPGA went out of its way to be fair. Tour officials did not find [out] about the Friday incident until after Wie teed off Saturday. After clarifying the rule with the USGA, the tour decided to let Wie finish her round uncluttered by the issue and then allow her to respond to the accusation. To her credit she verified the account.
To think this is some vendetta against Wie is simply wrong. According to the LPGA, her's was the fourth DQ this year for failing to sign, one of which occurred after the player in question had taken only a step outside the scoring area. Last year there were at least six such DQs.

I don't believe anyone sees this as an LPGA vendetta, do they? Seems more like LPGA incompetence or budget restrictions. Incompetence gets the nod here because, really, ten DQs in the last year or so?

In the interest of players, fans or sponsors, at what point do you (A) put an official in the scoring room (B) get local LPGA or PGA members to man the scoring tent or (C) put up an enormous sign on the back of the door saying, SIGN YOUR CARD, LADIES!

I contacted the PGA Tour to find out how many times a player was DQ'd for not signing their card in the last year.

Zero.

How many times this century?

Zero.

The last time that a PGA Tour player did not sign his card was 1997. 2005 (see JohnV's link below).
