4). The @leo.voter is the Steemleo community voting bot. Send LEO to it and it distributes a portion of the bids to delegators and burns the rest. The voting account is already at 100k SP and is burning (at the current rate) about 100+ LEO a day!
What are the limitations? I tried twice, at an 11 hour interval. Both attempts failed (“next_round_full” error messages). I was trying to burn 50 Leo, is that just too much?
