If I am following your premise correctly, you believe lauda is a "high risk" to newbies because, in 2014, he was saying that some altcoin was not an instamine coin, and in 2017, he changed course to say the altcoin is an "instamine scam"
Do you think additional information could have come to lauda's attention in those three years that might have changed his mind? As opposed to malicious intent?
I've heard this accusation leveled against Lauda before, and it never altered my respect for him/her. Though facts might not change, people's perception and/or acceptance of the validity of those facts may change over time--and thus people's opinions may change over time as well. I don't think Lauda's stance on any of the instamine stuff is grounds for a flag, a tag, or anything else.
And yes, Lauda, even though I've ~'ed you on my trust list I still do respect you. I just think you've gone way overboard with some of the feedbacks you've left. Not that it probably matters to you, but that could be a temporary situation depending on what you continue to base some of your negative feedbacks on.
