That is no more spamming as he was deleting the old post. The moderators will leave his account alone and not give it any temporary or permanent ban. But what could teach him the lesson is when his account has been given comments on his trust page about what he did. If a campaign manager reads it, he will think of selecting him into another campaign or not. But I do not think a campaign manager will select someone like this that intentionally ranked up and start looking for all ways to earn money from a signature campaign.
