I was going to send you 1 Merit for this post but I checked out your post history & its littered with Bounty Hunting spam so Im not going to now, sorry.
Youll never rank up if the majority of your posts are in that shit hole of the forum. More posts like this though & youll rank up.
I always find this argument really funny. This is the one reason why so many newbies argue that it is really hard to earn a merit. They will post a decent and high-quality post and you will point out that they do not deserve it because of their other posts. Then what will happen? that newbie will be discouraged because he cannot remove/delete his past posts and cannot turn to a new leaf and will be forever be judged because of his past post and will never earn (or be lessened the chance to earn) a single merit in the future.
But it really isn't hard. People shouldn't have to just make one good post and then they're good to go. Any idiot can do that, and once they have it they then don't have to bother making any more good posts because Christmas has come early for them. They can just go back to shitposting again, so that's why they should have to demonstrate they're not a one-hit wonder and can make a handful of decent posts. This is why I would argue we should make the requirement ten merit, and I actually think it will make things easier for everyone. People will be more liberal with their merits and so users are more likely to get merited, and shitposters won't be able to abuse the system as easy. When one merit is all you need to earn here people become weary about giving that user a license to get paid, and making one solitary good post really isn't enough to measure their capability especially when you can just beg, buy or trade the merit quite easily.
But your argument neglects one thing, and that is the hierarchy of ranking. There is a reason why we need different number of merits per rank. If that member deserves that one merit, then he deserves it. If he will get another merit from other posts from him, then that will depend upon his future posts.
Merit system is introduced to reduce spammers (and it is really working). More than that, it is to prevent spammers from ranking up. If that spammer only deserves to be in jr member (because he only made one good post that deserve only 1 merit, then go for it), and merit system already doing its job of letting that spammer stay in jr member forever (member needs 10 merit).
Or you just want all the spammers to stay in newbie forever? I think you are fighting a losing battle in this part. You will never able to completely eradicate them, but at the very least the current merit system is preventing them to grow in numbers and rank up at the very least beyond jr. member or member.
