Apart from the fact that legendaries are more likely to be good content posters, let us consider this;
The merit sources who also are more of legendaries have been here for a long time. They have been meeting one another here for many years, apart from the content of the posts, they have falling inlove with the writing patterns of one another, their tones, how humorous, commanding or entertaining they will be. So, meriting such posts becomes a habit, most times without paying attention to the contents.
Although the hero or legendary members who have been on the forum from a long time and tend to know each other will not give any merit to other if the post quality don't match the meriting criteria or is not of that quality.The writing patterns fan following is obviously there like @JJG is famous for his long and elaborated wall of text giving replies in depth and explaining the other members but you can't say he is writing something off-topic or dragging up the topic so if other legendary members merit that post it's fine and worth it.They might give some extra merits compared to newbie account but not on the verge of ignorance.
Secondly, the law of reciprocation is indirectly playing out. Merit seems to flow to those who has the ability and enablement to reciprocate. A Merit source can easily give out 50merits to a legendary fellow, knowing too well that it is cyclical, re-genaratable and reciprocal.
Sometimes merit sources help each other if they eun out of merits to allocate the same to other quality posts on the forum.We can't say they are abusing the system but in the end they are not going to hoard them but spend all of them as they will regenerate them next month.You can see most of the sources are ready to help new members also to rank them up only if they gave good out of their posts and contribute effectively.
Finally, I believe merit sources do not give higher merits to lower ranking members because they believe they may abuse the smerits they will have as a result of the given merits. It's somewhat showing that the merit system works in conjunction with the trust system. If you are trusted, you are trusted with merits too. Knowing too well you may not play the hide and seek game with your alt on merit issuance.
Like many new members have got many merits for their posts like @Rainbowkun,@Kaggie and you yourself why? Because you all have contributed for the same.You will find many such members in local sub-boards also with 30-40 activity and more than 200 merits gained with account registration this year only.This is because they are getting merits from legendary and sources.
I am of the opinion that lower ranking member(s) who is able to produce a few quality posts, can be trusted and has a decent history of smerit allocation should benefit evenly because they are the future of bitcointalk.
Thank you!
No doubt they are future of the forum but it needs to be tested that whether the future is in safe hands or not and that takes time to judge the writing style of newbies account and if they continue to the same and effective posting the rewards and rank up are on your way.
I'll admit I know which Hero & Legendary members tend to make quality posts, but I try not to merit them often, and if I do give them merits, it's usually a small number. I do try to save merits for lower-ranked members, and I love it when I can help a deserving individual rank up.
I have noticed the same thing that you help most of the members who are quality posters and contributing to the forum and left with little merits to rank up you help them by giving them required merits.Every member have his different approach of sending smerits and the main purpose is to merit the good posts in any way you can do.Your way of helping inspires lot.
