They did that once, three times in a day and I won twice. Lately I've seen as much as 200 points at a time, (along with 25, 50, 75, and 100) but they do it multiple times a day. You've just got to be lucky and do whatever you can to increase your amount of clicks to the maximum of 100.
The star rating is at the top of the thread where the facebook, twitter, etc is at. Not a huge deal, but I'd like to think that if I'm being informative people have no reason to rate my thread down. I answer a ton of PM's and questions in the thread and, while I'm really trying to make a dollar out of fifteen cents for my own benefit, there's no reason anyone can't do it for themselves. I got the idea from other people and I've just stuck with it, at least I don't type 'bump' and run.
