When start forum 2009, rank policy system only activities then 2018 change forum rules rank up policy merit + Activities , I ask @theymos again any Possibility change forum rules upcoming future.
At first before saying something, you need to have basic information and know a little story around it.
Let me tell you that at first there wasn't any activity requirement to rank up, only post counts (Since there are no limits on post per day, it was useful against spammers).
Then there was added activity requirement, 1 activity in 1 day, automatically but in order to activate this activity, you have to post so 1 post activates 1 activity point. It created a barrier of not ranking up immediately, for reaching SR member you need 240 activity that means that 240 days of wait and for hero - 480. Still it wasn't a problem because people were registering accounts and starting posting later (you can register and wait 40 days, post 40 post in one day and get 40 activity). So alone this automatic system wasn't enough, then the merit came.
As for now alone post count and activity point don't have enough power to rank you up because in 2018 merit system was implemented, now only the combination of these 3 can boost your rank. System can't give you merit automatically, only users can. So this makes ranking process more manual based and combination of these 3 makes it more difficult for spammers to rank up. The only other thing that comes to my mind for far strict rules is to make ranking process 100% manual, i.e. when person has 240 merit/post/activity, then this account moves under Staff's review and he/she will decide whether this user really deserves rank up or not. But I hugely doubt that will happen.
You want to read and post on this forum? It gives you possibility of that without limitations. Want to post images? Then buy Copper Membership. Want more signature space? Then consider this: Quality over quantity.
Good luck.
