My honest feedback about the whole incident is as at below.
There's a particular Co-Leader who likes to abuse his power, demote or even kick people out of clan when their trophy count is higher than him. 0 donators with high trophy count get to stay while active donators with slightly lesser trophy get kicked.
It seems the clan is make up of Secondary School kids (some of them are classmates cum Co-Leaders) who are having school holidays who can have the luxury of playing whole day. To make matters worse, Co-Leaders have been stressing clan members to push trophy on Ladder mode all the time or else they faced the risk of been kicked out from clan while at the same time attempting to rise up to top 100 clans locally.
Quite a few victims already but nothing has been done. There's a Co-Leader who was unsatisfied with how that person run the whole clan, consistently screwing things up and decided to downgrade to join Aura.Lemon.
Objective of playing a mobile game is to have fun and not get stressed out especially how fast paced the society has become.
Quite glad to be out of the clan, can finally play at my own pace and do my donations, requesting of cards as and when I want to.
Peace out! #endofranting
TLDR: Don't bother investigating, they will cover up the whole incident since they are friends cum classmates cum Co-Leader/Leader.
