@Fivestar4everMVP, I saw full members just applying when they crossed 75 merits. For full members, 25 merits is a big amount. If they get this rank easily, then they will be discouraged from contributing to the forum. They should earn at least 90% merit before applying here. Above Full Member 25 is fine; that is in your current rules. That's the reason sometimes I ignore full members. I don't want to let them be lazy. I believe merit limits would be different for each rank.
My advice is below.
To apply here, applicants should have below-average merits according to ranks.
To Members: 9 Merits
To Full Members: 90 Merits
To Sr. Members: 225 Merits
To Hero Members: 450 merits
To Legendary: 900 Merits
It's just my advice; maybe some +/- would be fine.
I have already proposed something similar here
https://bitcointalk.org/index.php?topic=5445913.msg63873169#msg63873169However, it seems to me that even with such rules, the majority of users will ignore it and after two or three pages, we will again be overwhelmed with congratulations and unrealistic expectations from here when it comes to merit. Someone expects that he will get more merit here than he managed to earn natively.
