Though, you are definitely misperception. Yes, most of the people are trying hard to earn merit by posting such "consecutive or quality posts" in many boards but I don't think if you just posting quality posts could gives you merit.
As per my conclusion, people send merits mostly because someone post is actually good to deserve merits and had a lot of contribute to the forum, so, posting such "consecutive or quality posts" doesn't deserve merit even if you had a perfect grammar but it has zero meaning toward your post.
Thankyou sir. i feel relief after reading your message, its like being bullied by high ranking members where i dont really intend to beg for merits. Trying to express your opinion and asking any other methods or advise on how to earn merits is my intention. Not begging for merits.
Other high ranking members belittle those who are just starting.
