Mods cannot explicitly enable privileges like that - You'll need to re-earn them like anyone else by posting quality answers. This is by design - its the opportunity cost of putting out a bounty, and something I urge folk to consider before posting a bounty.
I'd also add that begging people to upvote you, through the misuse of questions and answers is bad form.
I'd add that the two questions you posted would be considered abusive, and I was inclined to stick you with a suspension for doing so. Reputation reflects trust and understanding of the system, and I see a display of neither.
As for downvotes - On the main site, they were completely deserved. I have no clue why you would consider things would have happened otherwise especially after I commented about it with your first question.
Here on meta, downvotes are a sign people disagree with you.
