You should do the task! Reasonable DT will not tag any participants until it is proven scam if Best change turns out to be a scam, then you should stop participating, But for now, do the task!
It's your own risk.
Good ahead do what you feel like. Just have it in mind that there is a risk of not being paid if things go South... right now people are just having doubts maybe until after week 1.
I'm doing the task and I'm not afraid of not being paid. I'm more worried to be tagged because of some other person actions and decisions

But I can not speak for every participant. That is why I've asked the question about possibility of being tagged by members, who already tagged Best_Change
