You said yobit campaign is closed.If that is the case than it is a high price for sr.member account
I mean yobit campaign is not accept new participants, but their campaign is still running.
There's still higher-paying campaigns than yobit for less work, and the price you're asking for is really high. I'd suggest you lower it as you're going to get lowballs and only lowballs. 0.006/day IS a lot, but that's with the maximum 20 posts, which is some pretty hard work; in comparison, there's campaigns giving out 0.007/day for only 10 posts.
It does have solid post quality, so you've got that going for you- I seldom see accounts with 100% post quality. I only have 89.89% as of now because I used to post a lot of short responses when I was a newbie and jr- that's 50% of the forum.
