Is facemask now universal protection for every problem including when smartmixerhelper makes mistake or accuse others for being Chipmixer alt accounts, without presenting any proof for his claims?

It's called deflection. They have been told how unbelievable and rediculous their claims are by many experienced long time members of this community. They are 100% positive they didn't make a mistake so them making it up is the only possibility left. Rather than address their credibility shortfall they double down on implausible claims so we argue about that to distract us.
