If he meant what he said there, then that may have been one of his last posts here.
Yeah, I am afraid that nutildah meant it when he said that he will leave forum for good in case if he was banned :/
Is the forum better off with that thread moved and nutildah banned?
Forum is definitely not a better place without him, and we all know that he contributed in many ways since he registered back in 2014.
I can't say that he is perfect and without mistakes but he didn't deserved this one week temp-ban that pushed him to leave the forum for good.
There is still a chance for his return and maybe someone who knows him better could send him PM asking him about this.
