There is a difference between spamming and promoting. Copy and pasting isn't promoting. If people would like the "promotion" and would upvote it, it would be way harder to hide the comment. Also nobody would just flag posts without a reason because flagging uses steempower and you could also use the steempower to upvote posts where you could get curation rewards.
