A better idea would be two spam rejections to reject the edit, four unanimous spam rejections to edit ban, and six for a 100 rep loss; all subject to moderator review, possibly hours (days?) later on some infrequently visited sites
A blessing and a curse, as the spam could be offensive; like the 'doll spam' - in any event there would be a mod notification, so it's not quite as drastic as the six flags loses 100 rep (as there's no limit to how many times that happens).
@Tinkeringbell I'm not sure I fully grasp your last paragraph in your answer. Are you suggesting I can now flag your answer and ask to undo a downvote and then you make that happen with the help of the CM team? For science I would like to try that.
@rene Eh, no :P My idea was that you could flag one of your own post / the post you downvoted and ask for mods to ask a CM to reverse the vote :P But like I said, bad idea to begin with XD
