If my instincts are correct, Vod is probably reassessing his commitment to bitcointalk and may be having a case of the "fuck its" right now.  He already posted that he doesn't want to be on DT or a merit source anymore, and he might be dumping his sMerits as a means of relieving frustration, if you can understand that.  Though Vod isn't voicing it, I think he's in a lot of turmoil right now.  This forum obviously means a lot to him, and I say that based on posts he's made in the past.  When you start detaching from something that's been near and dear to you for years, well...you can do strange things--actions sometimes speak louder than words, and it seems like Vod is doing this stuff in lieu of writing about whatever he's actually feeling.
