I think it has something to do with your number of friends at least in part-otherwise it seems kinda weird that someone who I only noticed bc they keep posting, deleting immediately, rinse repeat did it twice again today and has 1208 of them... 1 feed, 155 dramas/films watched, no lists/reviews/recs, 4 edits... and the big activity=over 500 friends in their 3.5 month stay here... another with >1600 friends has 3k karma. Apparently that's the bigger factor-bigger than contributions. Maybe hearts GIVEN has something to do with it, even. Feels like being racing horses and people behind the wall gambling, raising and lowering our stakes and our worth in turn, but I'm not here for validation of me, only my love of great dramas. :P
