In general, I like the idea. Maybe creating more sub-boards. Spammy boards tend to encourage to spam more.
1. Disable posting on altcoin announcements below Jr. member rank. Keep only read mode for newbie rank.
I doubt that's a good idea, many (legit) Newbies are only coming to ask a few questions there and if they can't do this it would reduce the benefit to make an announcement for every project. I agree, there are lots of paid spammers, but we can't restrict every Newbie to catch the spammers. 2. For reduce spam from others board just disable signature below member rank include copper membership. Peoples are skipping merit system and buying copper membership. Let them(newbie) earn from other campaign. So they are continue spamming.
Agreed 100%. Copper membership is just another option to buy a member account. Since 1 merit is required for Jr. Member most spammers decided to buy a copper membership instead. It seems to be more profitable obviously.
