That is true a person could do that....and others can downvote that. At this point, there are a few who enjoy those perks of being able to do what you described but I am not sure how long it will last.

As more people come on here, we are going to see the reward pool diluted. That means power will be in the hands of other people.

There will always be a few who take but, over time, if most embrace the mindset of helping others out and posting quality content, those who are outside of that will be shunned.
