What this smells like, if I were a betting bot, is that these individuals are taking a similar stance to @transisto's recent defense of his involvement with the @zer0hedge account saying that cashing out SBD's is a "hedge" against prices falling, as someone who is heavily invested in SP. That in itself is an understandable position for someone to make as an investor.

These people delegating to sweetsssj in this case might be wanting to deflect the public rage onto someone who has already been seen flagrantly abusing delegations and the pool before with such behavior, so her public image can't really take a hit when it's already been destroyed, and they attempt to shield their own accounts from such accusations and save face while cashing out on the side.

Just a hypothesis. They'd probably rather be known as the cool guys who support cool things, not the people who upvote crap at the last minute to make sure their bags paid something out along the way. I can't blame them, just look at the flack sssj is taking right now.

Are the 2nd and 3rd accounts you listed even people? They're delegating out all their power and don't post anything.
