Is there any law on steemit against self votin ?
There's no law, but as most of my SP is delegated to me, I don't think the purpose of this is to use it on myself. I'm going to do a vlog soon and explain my point of view a bit more.
is there a special reason they are on the list or were they selected at random?
A bit of both, siding with the 1st point these days I think. @fulltimegeek is in charge here, I just present the stats :)
Cheers!
