Those who are mean to you here with no reason are all one type of shill or another. Either 1. they are trying to limit Voat's success and sabotoging it's expansion or 2. they are trying to secure it as a circle jerk and squeeze out other ideas.
None of this I'm sure is anything you want to have to worry about in what should be a peaceful migration but when the undeserved hatred comes you will understand why it is there and that it does not represent the vast majority of us. There may even be a few who are not shills who picked up the shills' pattern.
You can use tools like AVE (amature voat enhancements, just ddg it), or use the much worse disposition tracker if AVE doesn't install.
Remember who was mean to you for no reason and then you will know who they are.
If you give someone a reaons to be mean to you and they are that's a different story, but when there is no reason at all you know there is some kind of other motive. Call them out on it. Do that and you should fit right in.
