It's like with any other tool - might be used for performing good or bad deeds. No tool will eliminate all risks and take away all responsibilities from the end user.

In the package you get the place for witnesses to "advertise". I would also assume that this is just an initial stage and might be fine-tuned later on.

If you're just here for the rewards you can delegate to the account (ivoted) or anyone you know who is implicated in the choice of witnesses. We will insist on that point on our next posts.

For sure it might be used to only get the rewards (and abuse the system) but then it's just the beginning, it might be adjusted depending on what we will see in term of behaviour. For now, it seems to be working fine and rewarding people who vote consciously but it may change in the future, if we see a lot of people entering the program.

As @pibyk said, it's an experiment and it will be fine-tuned as we go.
