It sort of achieved that.
Why sort of?
Well, there is no spam, just quality posts.
However, how many of them?
Once we've removed the incentive from the posters, we witness a mass decrease in posts overall.
There are spammers in other sections, but we must not forget genuienly good posts are incentivized too which makes them quite active unlike Ivory tower which gets a reply once a week or so.
Compared to the other sections which boom with activity.
Besides, since merit was introduced, there really isn't much incentive to spam pointless posts, since you need quality posts in order to rank up.
There is some incentive for people who have already reached certain ranks to spam, as to fulfil their sig. quotas.
My personal opinion is, although there is obviously some negative effects from sig.campaigns they are most certainly good for the forum overall.
They incentivize people to be active.
They help create active threads, sections, SEO rankings etc. etc.
Why do you disagree? Or do you agree
Totally disagree.
There should be junior boards for bitcoin and altcoin discussion.
Just like the old noob jail. Instead of reporting scams and shills and generally doing negative stuff to remove these types. One could spend time on the junior board rewarding good effort there enabling their entry to the senior boards by giving merit .
It would be a decentralised way to mod the boards.
Of course you will find those that can game it to an extent. They will be deleted and perma banned.
Before the first icos the sigs were not even used by most members. The discussion and environment then was WAY WAY better and more active. Activity by real posters who had real opinions not people just posting anything or regurgitating the same comments for 10 pages.
Ending noob jail was a big mistake but it was of course inevitable in it's old form.
