I don't know but for Lauda is still a person that catches a lot of spammers and did helped the forum on many ways, with continuously searching spammers/scammers and whatsoever then of-course you will be a hated person by a lot of members as well and many will try to stop that person and....
So I think he/she earned a lot of credit by helping out, I do remember having a question and being answered prompt (don't remember the matter instantly, but it was fast) Then again if the red-feedback was only on that merit post that was saying something over highly respected members then I would say thats over the line.... Imo I would say its fair to remove the red and maybe make a neutral in which you say something but red-feedback isn't at its place (for me).
