StumbleUpon - My “algorithm” to deal with friends limit

I like StumbleUpon. My website gets many visits from there. But as many ( blahblahtech and traffikd ) I have an issue with the friends limit.
Said briefly you can be fan of at most 200 people. After that you get a warning and you cannot add more fans. You cannot even reciprocate a fan of yours. So you are in a kind of deadlock.
I devise this sort of algorithm to deal with such a situation:

• Become fan of a friend
• if he reciprocates fine
• if he doesn’t, persuade him to unfriend inactive people he is fan of
• if he doesn’t reply for a while unfriend him, because he is not active or does not share any interest with you

In Actionscript

var limit:int = 2; // weeks

for each (stumbler:People in peopleYouAreFanOf) {
	if (!stumbler.reciprocates() ||
            !stumbler.persuaded() ||
            stumbler.getRepliesWithin(limit) == 0)
        {
		stumbler.unfriend();
	}
	else {
		you.sayThanks(stumbler);
		you.interactWith(stumbler);
	}
}
