Hi there @danghao it's sad what happened but don't give up you haven't been blacklisted I enjoyed all your blogs and people do make mistakes but please try and give it another go and just see how people react worth the chance to find out.
Just to remind you @beachwednesday and @sunthursday are back do a post on one of them and see how it goes but you will not be able to do a post on @beachwednesday because you won the last one and you will be judging the next contest on April 12th hope you can be there to do that.
