The damage has been already done and you have been cheated.
You should know from the start that cheating isn't allowed here by using multiple accounts.  There's nothing we can do to remove the tag under your profile if the one who tagged you will not give a chance.  Do something convincing that will change her/his mind to change it into a neutral tag and promise not to do it again.  If it will not, just move on and find a real job, this forum is for the discussion and sharing knowledge about bitcoin and blockchain, isn't the sole purpose of making money or even spamming the bounty section.
