I think you've been marked for upvoting your own comments on day 6 and this behavior is frowned upon by the community that disagrees with the habit. It's not directly an attack to you as person but more on the habits that discourage milking the reward pool behavior. If you admit to the fault, willing to change your voting behaviors for the better, I think there is still a way to remedy the lost rep.

You were just fine earning from your account and upvoting stuff until the recent development of voting on Day 6 especially on a circle of accounts, going to give you the benefit of the doubt that you didn't intend it but these are the same behaviors that people that exploit the reward system do thus why it is frowned upon. The blockchain still holds the records if you indeed voted on day 6 on those account so if one can trace the time stamps.

I do apologize if my downvote did hurt your feelings. But that was just disagreeing with the rewards on the post and nothing on the personal level. I do hope you reconsider your stance on the matter and take a step back and contemplate what happened. I don't speak for the people that you think have done you wrong. But I think showing some tact not to aggravate the situation and negotiate it better may be helpful.
