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.

Inbox pakhitheboss about this and see him remove the tag. Also PX-Z already explained to him in the thread.
DM him and if he refuses to remove the neutral tag, you can drop a counter neutral tag on his profile and maybe distrust him if necessary, and move on.
