I don't understand why many people relate poor quality / shitposts /spam posts to newbies or lower rank members. this is 100% wrong.
why would you limit a newbie who has a huge amount of knowledge just because he recently joined the forum?
look around the technical and series discussion, you will be amazed , many members who joined recently are top notch geeks.
allow everyone to post, let the members decide who is worthy and who is not, by merting and commenting on quality posts.
Does what you just wrote above contradict anything I just wrote a couple of posts above you?
Putting a restriction on newbie's signatures doesn't keep any of them from posting. It just keeps them from earning money from their output, which is usually a bunch of shitposts. If the solution was merit-based, a legitimate newbie member ought to have no problem earning whatever the requirement is, albeit probably slowly--but that was anticipated since the beginning of the merit system anyway.
It certainly fits what OP wrote and what I gave a personal example of in my post:
There are just so many low quality posts that sometimes makes me feel as if nobody reads the topic but rather just rambles non constructive answer based on topic title.
In other words, you're making a non-argument and I'd already written how restricting newbies/Jr. Members from being able to advertise in their sig space doesn't prevent them from making all of those brilliant posts you claim they do.
look around the technical and series discussion, you will be amazed , many members who joined recently are top notch geeks.
If that's true, then they shouldn't have a problem advancing in rank if that's important to them. But if you think it's not the low-ranked members who are the primary problem, obviously you haven't ready many threads in Altcoin/Bitcoin Discussion. Not to mention the rest of the altcoin section, the ANN, bounties, and tokens parts in particular. The shitposting noobs have also started to infest Economics, Trading Discussion, and Speculation as well. Go read some threads in all those sections and then tell me if you disagree with me 100%.
