I noticed that their ANN thread in that other forum was locked. Apparently they wanted to open another thread, which never happened ( It was probably their plan to convince julerz12 to keep it locked). Maybe you can advise julerz12 who opened their thread to keep it open such that people can report an ongoing scam under that thread. Otherwise, some people will never know what's happening.
I am not sure if there is a red trust and flag system over there as well.
Officially, Yomix did not appear on that forum. julerz12 opened that thread as part of their campaign a long time ago, but considering the events of the last month, he decided to close the thread. It is a good decision to lock the thread, maybe julerz12 could add some warning in the header.
I don't think there is any plan from Yomix, because no one has contact with them.
As far as I know, there is no part of that forum which deals with scam accusations against different services. Most often about members who received penalties due to abuse or cheating in bounties.
