Gone are the days when updown.bt used to offer 0.0007BTC/post, those days the competition was tough, nowadays almost no one is interested in investing in member's signatures because they are not colorful + short in height and length.
This time the bitcoin market is going through a phase of recession, wait for the websites to grow and then you will start getting good rates for signature campaigns.
you said less than bitin.io but lol you are asking 0.0009 per post bitin.io pays 0.0001
I am getting a gut feeling that he wanted to write 0.00009BTC/post and by mistake he wrote 0.0009
