Meanwhile, I will advice them to set atleast 30 minutes post gap.
There we go - pretty decent idea. Yobit (or any campaign for that matter perhaps?) should count a maximum of 1 payable post per 30 minutes or maybe 3 per hour (1 every 20 minutes).
That would be a great idea.
I massively doubt they're going to allocate the amount of time needed to check that. Considering the number of people who've piled in they'd need to tie up an employee not too far off full time. I'd be very interested to know what resources they have chucked at it. They may only rely on complaints or just keep going without looking at anything until it reaches a critical mass of annoyance.
I am still a member of the old campaign, and there the counting was done by a bot. I think that it can't be too difficult to add some code that measures the time between posts. This way a 30 minutes gap for paid posts would be easy to controle. I find this a good idea!
