Proof that the BTS members have created their Instagram accounts long before, Jung-kook has even made his 6 years ago?

Jung-kook has created his Instagram account long ago, far before the recent official announcement.  

Even though BTS debuted 8 years ago, but not until Dec 6th this year did the 7 members officially reveal their personal Instagram account. As of now, BTS is currently the most-followed boy group on Instagram while the members also gained hundreds of thousands of followers in a short period of time.

However, what’s worth noticing is that, netizen recently discovered that the BTS members have created their account before Dec 6th while Jung-kook has even used his account for 6 years since March 22nd, 2016.

Among the 7 members, j-hope is the only member whom account’s detail cannot be viewed yet, which means we still don’t know when he created his account. Netizens have talked about Jung-kook having a personal Instagram long before this, but no one expected it to be a 6-year-old account.
