As far as I understand none of the people who are being warned for upvoting are given a copy of the post that triggered the warning. This makes it quite difficult for people to adjust their behaviour because they might be upvoting content the genuinely believe is not breaking the rules. If you weren’t assuming good faith on Reddit’s part then you might suspect they were doing this so they could distribute warnings to users who were supporting wrong opinions. The more innocent explanation is they either overlooked this or they don’t want to distribute the rule breaking content. I believe twitter often shows you a copy of the offending tweet when you get temporarily suspended.
