How is it going to resolve the problem? Because of the tag you left, many campaign mangers will deny him joining their campaign, companies will deny him to give their projects, resulting he is not going to financially benefit from the forum. As per his explanation the forum is his only earning source. sucks but it's reality for him.
It's a delusion. I, like other managers, have repeatedly accepted users with red tags into the campaign, especially when the user has more green tags than red tags (we are not talking about tags associated with outright fraud). No self-respecting manager will remove high quality posters from a campaign just because they got a red tag, this rule is more like a deterrent factor for those accounts that generate spam (as far as I remember, you also participated in the signature campaign when you had a red tag ). 
Hopefully you don't mind the yellow warning too.
I've left him a neutral tag but I think a negative is acceptable. He himself has acknowledged that.
I don't call it happily accepting but to accept because arguing is not going to help him. I see a surrender there because his voice are weak now. I don't call it acknowledgment for real. Stop being JollyGood (sorry man JG, no mean to discredit you, you built up your own identity). Give the man a fair chance. Red tag by icopress is fine everyone, he has all the right to make that judgment, kindly stop bickering about it.
I am sorry, maybe my responses are not diplomatic like many others but I like straight talk. The forum do not need policemen and a crime bureau to spy others all the time.
