Hi meano lol. I suppose you have to put yourselves in their shoes. Let us say this particular person is so big that they don't need the community. This person posts numerous posts a day and makes $2000 per day or $60 000 per month. This person is milking the system but not really breaking any rules. It is frowned upon by the community but there is little anyone can do. There are issues that I think need to be fixed to prevent it and most likely won't happen. Multiple accounts is one and self voting is the other. This won't fix it either as the individuals will find loop holes and will carry on in another form of self payment.
The reward system plays into their hands as they are big enough not to worry about the community. In some cases they are like a corporate giants that will only get bigger and bigger and changing the system is the only way of stopping them. Greed has made monsters who just want more.
