Yes as long as it is legal (can't imagine it isn't) there isn't much to be done even if we find out who it is. However I guess if they know how many shares left, might give insight into when it will stop (when they run out of shares to sell).

Thanks Roni1 for posting that, it is interesting info in any event. Sooner or later when good news comes out, volume of trading will help, right now in my opinion 100K shares a day or so is super low volume, so easily manipulated by selling/dumping shares. Won't be so easily manipulated with volume at 1M and people are buying, then someone can dump shares as much as they want.
