There are no rules that say Legendary ranks should send their merits to a certain rank, or what percentage of merits they should send to newbies. The only criterion for awarding merit should be a good and high-quality post, although each member of this forum has created his own criteria over time and quality is not something that is decisive in that decision.
Maybe the admin should have created the merit system in such a way that it prevented Legendary from getting merits from the same rank, or the max amount of merits should have been set to 1000, although that would have opened some other issues in the distribution of merits.
As for Altcoin boards, the forum long ago admitted defeat regarding spam and scams in that part of the forum, and I'm just one of many who don't want to participate in it, at least by rewarding newbies who hunt for bounty prizes there. I hope that we send the message so clearly, and some who understand it will be rewarded for it in other parts of the forum where they can actually learn something and become part of the community.
