I thought people were allergic to bots spamming warnings. There's already a penalty in place for those voting late on curation but these hardly ever discourage anyone especially with larger stake to game the system. The issue was him doing it whether he may be intentionally doing so or just happen to like supporting the same crowd on day 6 old comments.
They can do that on fresh 1 or 2 day old comments than be suspiciously doing it on day 6 for what? Now it's not really right to assume intentions here, he might have meant well or he did try to game the system, who knows, what is sure is the voting behavior was done and these are the consequences.
Anyone is still welcome to counter those downvotes or reinforce the downvotes of course. I don't see him ever having a problem further unless he consistently does it even after all this. Aggravating the people that also downvote is also a bad idea. I mean, how hard is it just to not vote on day 6 and go for fresh comments instead?
