Weatherman is playing the numbers game. The more posts he throws out, the more items are available to be captured by the web net when someone searches his target. I'm sure he doesn't think of it as time consuming; rather it is a small time expenditure for the revenge he feels he is getting. Regardless of how weary other readers grow of his repetitious and non specific posts, I imagine he will continue with such posts as long as he is allowed to do so.
