up bots?

I've noticed over the last week or so a, mostly futile, bot attempt to put a floor under the sp.
It (the bot) is still ramping today and I'm wondering why?
Who would benefit from a higher sp in the short term?
Somethings afoot ... and I haven't a clue as to what!
Artificial attempts to prop-up a sp are never a good sign.
Thoughts?
