Can't we develop some mechanism like Reddit or other forums where every user have equal right of voting on a post.
It is a good suggestion but the problem is that this can be abused here a lot by creating multiple accounts. The merit system is able to fight against this because new users do not get any merits to abuse at all. Also, the default merits of even higher rank members is spent by now so we are equal.
Now it has become like a system of monarchy Where some members are behaving like a king and announcing like they are throwing food(merit) come and beg to them.
Use ignore option for such users. On an online forum , you will meet different kinds of people, some you do not want to interact to.
