Obviously any scam buster will make mistakes, if you only mark the confirmed scammers then you are doing nothing because everyone would know already. I consider his ratings helpful for the community, yeah if some of them are later proved wrong then he simply can delete them and problem solved. Afterall he has a 95% accuracy and im sure he prevented plenty of scams on this forum.
Relax dear. I know that you love him. It's not in mine or your hand to make him the MOD so why argue
He does make mistakes, but doesn't correct them . You can't really argue with him if the accusation is on you , even though when he is the one wrong and you offer proof for everything. He is an overly egoistic attitude with things going in the opposite way for him and will never agree to his mistakes in 99% of the cases. There was also worshipper he gave a negative trust just he denied using him as an escrow. I have also seen him to unethical things like removing trust from a confirmed scammer just because he used him as an escrow for selling the account, but didn't care about the trust on me even though I provided enough proof .
I feel this was the case earlier but now he seems to be in control. He doesn't jump to conclusions. Anyways, MODs don't have the authority to ban users unlike Global MODs and hence if he can manage the reports carefully of spammers, he can be a good moderator.
