Duplicate isn't for your own self-pity. It wastes people's time having to either monitor your edits or undo wrong changes; and for example, earlier today, you did this to a perfectly approvable post like post #10549325 so approvers would be hesitant on a first pass through to approve it without stopping and checking closely. It's also not helpful to someone who might go through your deleteds and see posts they like but they're all tagged with "duplicate" so they'd be hesitant to undelete it.
You need to find a more meaningful way to cope about this. Edit warring is not the way.
Leaving any posts, but especially rating:e posts, with barely any tags for nearly 2 hours is not acceptable. Telling others to not tag those same posts is even weirder.
