What can I do to get back my member rank.

Abandon the acc farming.
I seriously need help, sir. Not an accusation. I am not farming this account. I made this account a month ago to offer signature design services, but nobody seemed to be interested. Now I used this account to ask for help and for the privacy of my main account. I applied to a signature campaign for a member rank, my activity was already 70, and then about an hour after, my rank turned to jr. member and my activity had gone back to 56. I do remember deleting nonsense posts at the games & rounds section and in other signature campaign threads before it happened because I thought that the campaign manager won't hire me if I have posts on those sections. Does it have something to do with my rank going down?
