How justified is to force participants to write 30 posts weekly in just three sections? It will clear-cut contribute to spamming.
Either lower the number of required posts or allow participants to write in more sections.
I agree with this one this will make a lot of spam if you will only accept a post made on that 3 section its better to at least say a section that will not count and add other sections counted like (Alt speculation and economics and many good section. or at least make the post minimum to only 20 post per week .
