Before I go on, I want to use this media to send my sympathy to all the legitimate forum users which rank got demoted from junior member to newbie. I can relate to how you feel (disappointed) just like when you participated in a bounty campaign for months and it turns out to be scam.
I have this little advice for you all, instead of spamming this forum with complains upon complains like others, I will advice you learn from the mistake you made and improve on the number of quality post you create. I known many of the demoted accounts were bounty hunters just posting, trying to meet up the required post to earn entries weekly but that's not how the system works.
You learn before you earn. So I advice you use this period to learn, if possible study merited posts, study how they're written (to entertain, educate or inform) and learn to write in those manner.
Lastly, instead of seeing your demotion as a loss, look at the bright side and see it as a blessing in disguise then utilizes this opportunity to improve on your writing skills. who knows you might be the next JET CASH.
Stay blessed.
