It is just a scam in another way
Do not explain the operation of the task clearly, which makes people misunderstand to do same operation as the first time. They use various reasons to show you that you have not finished the task or finished it wrong. It cannot be returned, but after the post from other people who have been deceived, it found out that all the people in the group are their shills.
Scam
The following is the original recommendation
根本是變相的詐騙
不說明清楚任務的操作,讓人誤會和第一次相同操作;拐你進5人群後,用各種理由表示任務做錯或沒做完,不能退還,但經其他被騙的人po圖發現,群內其他人根本都是他們自己人
