I tried this out by sending 3.5 SBD to 3 different upvote bots for two articles.

I directed the bots to two different article posts. One of them was 4 days old and the other 1 day old.

3SBD went toward the newer post and so far has 5SBD in rewards.
0.5SBD went toward the older post and so far has 0.86SBD in rewards.

In addition, as a result of this boost. My latest post has over 4SBD in rewards.

And... My reputation score has increased by 5 points.

Therefore, so far, this seems like a great way to help boost a steemit account.

If you guys are interested, let me know and I'll report back with the final totals after the 7 days are up.

Thank you,
