I understand that the spammers and bot are a bigger issue than a regular person getting a merit to be a Jr. member. But what I'm saying is that I'm a regular person, having regular conversations, posts, and so on. Even though I understand that the spammers and bot are a major issue, I'm just trying to bring light how this really messes up a regular person.
How does it mess people up? People should earn their ranks. If you can't contribute anything merit worthy then you should remain at a Newbie rank. Asking for one merit to become a Junior is not a ridiculous proposition. The other ranks are much higher.
The difficulty is such now that instead of developing through natural conversations, I have to go above and beyond and create really amazing posts. Most regular people are not going to have that ability. So you can see how it hurts the regular person the most.
Above and beyond?

. I'm really sorry that you now have to put a little effort into your posts and can't just rise through the ranks with generic one/two line posts. People are tired of having to read nonsense by lazy idiots who are only here to earn and do so by posting crap all over until they get the rank they want. If you can't get merit then you shouldn't move up ranks. People shouldn't be allowed to just come here and write "I like bitcoin because it helps me with my daily needs" 30 times and then become a Junior Member. Earn that title by posting something worthwhile, but if you don't then you should remain a Newbie.
Like I know I can go back and improved what I just said if I spend a lot more mental effort and time going over and looking at how I can better express my point. But now instead of being natural and a regular person, I'm forcing myself, using more mental energy, for the hope of getting a merit.
The cost, energy that one has to use for hopefully getting a merit puts us at a disadvantage.
Well maybe this is the problem here. Laziness or 'lack of energy' shouldn't be rewarded. If you lack energy to post on a message board then I wouldn't suggest finding something less tiring to do or just stick to collecting bounties until you've earned the right to move up ranks.
That means the majority of this forum can't write meaningful posts, isn't it?
Correct. Out of more than 2 million accounts,
less than 1% has received 1 or more Merit points.
The majority of users are either spambots or bounty hunters/account farmers with dozens of accounts.
Why are they not banned then ? Is it because the forum needs them for some reason or another ?
Bots are banned once spotted or reported, but their accounts still remain in the database, they just can't do anything with them. Alts are allowed by the forum as long as it's not to evade a ban or something else malicious.
