Currently, the name for KARD's official YouTube channel has been changed to '??', which is KARD spells backward in Korean. The group's profile photo has also been deleted. 

Another DSP Media group, A-JAX, are experiencing the same issue on their official YouTube channel. Their name has been changed to '?? ??' or 'JAX A' and the profile photo has been removed. 

So far, no videos have been deleted and there are no other changes. It's assumed the changes are the actions of a hacker or the agency is experiencing technical difficulties. 

What do you think is going on with their YouTube accounts?
