I love it. "No one specifically wrote do not copy delete and repost my "work", so I've been wronged". Oh this forum it's a gem that keeps on giving.
You're right there was no rule, but what always existed was professional standards, seeing as you see this as work and not just a benefit to engaging within the forum. So given that companies can see that you don't even feel responsible for leaving posts up for the duration of the campaign when paid for it, I imagine you're out of work. This problem has sorted itself out with a precedent instead of a rule, amazing.
You got greedy and wanted BTC for doing nothing and felt you were entitled to it. I would support any flag created by a company that you advertised for and did this to.
