No..I think 2weeks is not enough to grow your ranking from newbie to jr.member..i don't know too what is the basic rules for rank increase..but me almost 6months now but my rank still jr.member hehhe
Because you are a spammer and a shitposter. Did it take 6 months for you to become a Jr. Member? No. It took approximately 4 weeks (2 periods). Which is why OP is going to rank in 3 days, when the next period starts.
So stop shitposting and maybe (just maybe) you will get 10 merit in your whole career as a shitbounty hunter so you can rank up to Member.
