@flo, that limit is one of the things that make this site so excellent. No matter who you are, you can award only so many points to any one individual member. That number is about 100—about 20 GA’s. (I think it’s “about” because it might not come out even, depending on how many come from GQ’s.) After that, your GA’s to that person still register in the GA total, but they don’t deliver points.
That’s why after a while you can see your record of GA’s go up and up, but almost nothing gets added to your lurve score. It’s harder and harder to increase. There are days when you might get 40 GA’s and gain only 15 points. This is a good thing because it keeps us from just boosting our friends infinitely high and otherwise gaming the system. Newcomers gain quickly and older members progress very, very slowly.
And you know about the 5 per question, right? Only the first 5 GA’s per post have the potential to add points, and they will add points only if they’re given by someone who still has any points left to award to you. After 5, they all add zero. So a post has the potential to add 25 points to your score, but it does so only if all 5 of the first 5 GA’s come from people who haven’t maxed out on you. Therefore it’s not only possible but easy to see 5 GA’s for a post but no change in score.
That’s why I wait on great great answers—so maybe newer jellies with points left to bestow will mark them and add to their score.
