Preventing circle-reps - one member, one score

On our site we have had alot of problem with small groups of people circle-repping each other to boost their rep power. I came up with a simple code modification (no plugin space for this) that resets all previous rep scores a user has given the user they are repping and then applies the new rep score to their reputation.

Esentially this removes the incentive for circle-repping and only those who get repped positively the most end up with the highest rep score.

In reputation.php, at line 160is find:

	// Determine this user's reputationlevelid.

and above it add:

	// MDP
	// Reset older rep to 0 and then get new count
	$db->query_write("
		UPDATE " . TABLE_PREFIX . "reputation SET reputation=0 WHERE userid=$userid AND whoadded=" . $vbulletin->userinfo['userid'] 
    );
	
	// Now get current reputation level
	$newrep = $db->query_first("
		SELECT sum(reputation) AS newtotal
		FROM " . TABLE_PREFIX . "reputation
		WHERE userid=$userid
	");
	
	$userinfo['reputation'] = $newrep['newtotal'];
	// End

Now when someone reps another member, their old reps are set to 0 (leaving the comments) and their reputation score is reset and then the new power is added.

No more circle-repping.

Yep. Works fine. Keep rep from being abused on our site - promotes those who have gotten more rep from a greater number of people versus the same people over and over again.
