In one of the social media , unfollow not allowed , even in supended , in OC just like that I think is reasonable.
a reason that makes sense if the admin follow or unfollow facilities to its members, it is because to be able to help each other and interact among fellow members in a question and answer forum. then if the admin provides penalties for members who do unfollow other members to the sensible thing.
well same thing i have also noticed about other categories as well. I have no idea why points reduces. admin may explain this clearly.
