Whereas hubski is full of people attracted to here from reddit being full of those who are racist, sexist, or due to wanting to have an alternate to reddit. Voat is an alternate to reddit that is attracting conspiracy theorists, along with every other group that adopts the idea that reddit's community at large does not like them, or that the mods are shutting them down.
People who believe that reddit's mods are censoring them and shutting down discussion, shadowbanning for talking about bad things (which is rarely true).
I find it interesting to compare and contrast the two communities. With voat being far more "reddit-like" than hubski is.
