How can I regain the confidence of the campaign and get another chance? Yes, I'm to blame, there were 2 days when I posted too fast. Please consider my request and satisfy, this will not happen again.
I doubt if you will get that opportunity again. Yahoo is a campaign manager who always requests participants to follow high quality standards when participating in the campaigns he manages. He even gives people time to adjust but by the time you are banned then that means it was too much.
The rules were clear but decided to ignore them anyway.
