Reactions on comments
The positive side of this implementation can be that bitcointalk members will be able to react on each-others posts. In overall, we will create statistics of high quality and low quality posters that will help us to identify spammers. When there are a lot of dislikes on posts, it will automatically alarm the moderator to remove the comment.
This can be abused in several different ways. Let's say I don't like you. I dislike every post you make. I tell all my friends and even members of my local forum to dislike everything you write. I even go as far as offering some incentive for members to dislike your posts. Such an organized group would make you look like a spammer and have your posts deleted. If the mods don't delete your comments based on our organized dislikes, it means they aren't respecting the system they implemented, however bad or good it is.
Feedbacks on profile
Users will be able to leave positive and negative feedback regarding to post quality (i.e. likes and dislikes) on user’s profile. How will it work? Well, it will help users to rank up along with activity and merit.
The rank up requirements have to be the same for everyone. Doesn't seem fair to introduce a system that measures some sort of popularity among Full Members+ in order to rank. Be it faster or slower.
This scheme is similar of invite system but very different, you are able to register without invite but you have to gain recommendation in order to rank up. What will be the advantage of this action? In order to increase your ranking, you’ll need to get likes on your profile from Full Members+. If someone decides to lie and falsely leaves positive feedback on alts, we will be able to identify alts and abuser users.
Can I rank up faster if I show my boobs
This is again adding popularity into the equation. Those who are more popular (for whatever reason) will get more upvotes and can rank up faster than those who aren't as popular. You might say, the merit system is not any different. But it is. Even those who the community dislikes are rewarded merits if they have the needed knowledge and skills.
Quickseller has a -13 trust rating, but he has earned almost 1000 merits. I immediately thought of him because I came across posts of his that are good. The reasons why he is distrusted aren't imported in this discussion.
