Did they count all the NCT units? Because I think EXO had the highest mentions out of any SM act for almost 3 years in a row now as far as I know.
I would think it would be hard to separate them out since even NCTzens may simply refer to nct 127 as nct in tweets..and the main NCT account itself references the sub units. Plus all the NCT resonance content was branded and discussed as NCT rather than necessarily by unit.
Red Velvet with noofficial comeback since 2019 being the 3rd highest GG on this list is just Despite what haters say they’ll always remain part of the top3 GG’s.
