Chinese nexus/network in A* conferences rejecting non chinese papers [D]

Recently lot of people are coming forward that chinese have strong network and are doing nepotism and supporting each other through a well known mobile app they use. if true this is big, I also encountered this issue in IJCAI 26. Please share if you have faced this issue before

ex in my case : the reviewer was angry because i didnt cite a paper, whose main author was also chinese.
