even if pictures are not allowed they could be nicer with the fans and say "sorry cant take picture but I will give you an autograph instead" (like JM did once)Their company is getting 532 things relating to them getting copyrighted out of which above than 400 have been successfully copyrighted.. 400 is not a small amount.. the boys themselves are the first thing that the company would have copyrighted for itself..so they just cant take pictures with anyone because that way they would be giving away copyrighted stuff..
And all kp0p companies have this rule..dont they..?!
We don't see any of other korean idols taking pics with fans either..do we ?
Especially TH could have done that on his situation....it was a private place with a staff asking so he was not going to be harrassed
about other idols I did a quick google search and found Blackpink Rose had no trouble taking pictures with fans in Australia
BLACKPINK’s Rosé Spotted Posing With Fans In Australia
For the Lunar New Year holiday, all the members of BLACKPINK were given the opportunity to take some time off in order to visit their families. Lucky fans spotted her with her family in Australia and got to take some pictures with her!
