Twitter shut Google out of their ecosystem quite a while back, so I can't see how that could have an effect with your Google ranking. Facebook never whitelisted or partnered with Google and on the contrary, have been rather hostile towards Google at least in public.
With that said, I highly doubt your particular efforts on those two platforms has any positive effect whatsoever. If you're "trading" likes or followers, good luck on capitalizing on that.
