Error on Melon chart

Artists' ranks were randomly changed on the chart. For example, When We Were Young by Adele went up by +2633

The messed up chart:

Pann: Did anybody see the Melon chart?

1. [+163, -5] Zico, EXO, Red Velvet, iKON, Song Mino, Lovelyz, Lee Hongki, Beenzino, and etc were affected. Fuck.

2. [+107, -1] What did the fans of the affected groups do to deserve this? Fucking Melon ㅋㅋㅋㅋ

3. [+94, -40] iKON's 4 songs were on the chart until 9 and then it charted out ㅋㅋㅋㅋ It was my first time of seeing My Type charting out. Trash Melon...

4. [+52, -2] The affected groups are the pitiful ones. EXO and iKON's ranks dropped by 20. It's even more upsetting to see the fans enjoying the error because their bias' ranks went up. Do you know how hard it is to chart high?

5. [+44, -32] Seventeen went up to #3 from #46 ㅋㅋㅋㅋㅋ

6. [+41, -3] What's more frustrating is that some groups' ranks went up and their fans are celebrating it ㅋㅋㅋ I'm frustrated as a fan of Lovelyz and EXO

7. [+39, -2] I was flustered to see Run charting out

8. [+21, -2] I hope Melon doesn't put the blames on other singers. All of the artists who got their ranks changed are affected.
