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.
Is little bit difficult to understand your question but yes, we had changes in the forum rules before and surely we will see more changes in the future.
Simply, the forum as a gathering place for people is undergoing different changes and accordingly the admins must also change the rules in order to protect the forum from spam and abuse.
It's impossible for all members of the forum to be satisfied with every change, but I think that the merits nevertheless raised the quality of the forum post and thus fulfilled its purpose.
