Why is BTS cp Zheng Tai restricted?

There are restrictions, such as all kinds of clips, with sound but no subtitles, no shots, and sometimes there are shots without sound. Anyway, some cuts are obvious, and several cp teams have been badly pushed, so it is still quite obvious. Coupled with the comparison between the early stage and the late stage, it seems that Zheng Tai was restricted from Smart's activities. Or because the fans yy is too powerful. .
