Had a quick chat with Coins.Game where I asked them why they wouldn´t care about Bitcointalk anymore and they told me that they will start looking into the forum and respective complaints again.
They are a bit slow in communication. Other than this, they have always been professional to me. Hopefully, they will get one person to manage the ANN thread.
They launched the announcement thread, run their signature campaign for a long time, not like one or two weeks but decided to leave, it's something changed their mind in their favorite marketing places and likely this forum was not their main concern.
With an update from efilatis, they shown signal to come back here, reply to the community questions or complains and the return will help their brand appearance on this forum as well as the brand reputation too. Disappear and be silent can give chances to some abusers to complain without any confirmation from the team that whether these complains are valid or invalid.
