Thank you, for the reply.
By every means you can vote however you please. No ones permission is needed. I merely meant vindication by it's definition.
Vindication: The defense, such as evidence or argument, that serves to justify a claim or deed.
You are not required to back up your claim if you choose not to. But just as anyone can vote or flag who they please, others are free to think what they will of those actions. Giving evidence in support of their case would vindicate these actions in the minds of others.
I'm not a fan of compelling others to do things outside of their will.
I thank you for your frankness and honesty. I hope you have a wonderful day.
