I am going to remove the neutral tag from his profile but let this be a lesson that next time onward close your thread after your query is resolved or such a situation can happen to anyone. I do not have any personal grudge against the OP but I feel he could have sent me a DM rather than creating a thread and accusing me of biased behavior.
BTW, this reply is the reason why I am removing the neutral tag as I could have edited it and kept it because someone forgot to close a thread when he was a Member and realized when I tagged him after he became a Hero member.
Why? Is it mandatory to lock a thread after solving an issue? It is your responsibility to look at the date before you tag someone. You were failed to do it and you are teaching someone a lesson by leaving a tag? Do you always lock a thread which you created years ago? You are gone too far with your main account already. Don't start the same drama with your alternative accounts.
