Actually you can leave him a neutral tag for being ignorant replying 2 years old post.

I've heard some campaign managers don't like participants that beating the dead horse, this is not about who the first user bump the thread, but if someone replying to the old post, they're one of them (it's different to users who replying to the new post).
OP, you are a hero member, opening a thread because someone left you a neutral tag is unacceptable to me. That is what a newbie should do, please don't promote the act.
I don't see anything wrong because @OP did nothing wrong in this case.
