I´ve seen so too, maybe my vote is not worth much but I think it´s worth more for a newbie than for me...
The auto-vote box is tricky, I didn´t see it until I was like one month in hehe.
Yes! I sometimes do that, randowhale is a useful tool but we should use it with some restrictions (The line we draw it ourselves). It is my way of not wasting my SP and spending SBD , that way I still have SP to share the love. It is actually pretty much the same, the reward is like 2 SBD and 1 SP if you get a 3-4% vote so you are pretty much even, but you have apost that is not worth 2, is worth 6 hehe
