I can't be bothered to track who votes for me. Some people may think they will get something in return (apart from their curation rewards), but I just vote on what I like and expect nothing extra in return.

Of course people will try to game the system, but from what I have seen there are others looking out for any suspicious behaviour and they find it all the time. I expect they run some sort of statistics on voting patterns, but that's not my field.

I've said many times that reputation is hard to gain here and easy to lose, so you may only slip up once, but it could be costly. If you come back with a new account you have to build up again and may still get spotted. Is it worth all the effort?

I think Hive is doing pretty well at getting rewards where they are deserved, but no system is perfect. Of course some people are favoured by the whales, but that is more incentive to spread the stake around.

Hive is still tiny, but we can already anticipate what could happen as it grows. It's going to be interesting to see how resilient it is.
