Subjective and tier lists go hand in hand. Past the early life of BBCP, people on jbbs mostly stopped making and discussing them. The only thing that still carries any weight over there as far as I can tell, is:
1. Famous people lists. These keep getting posted. R1, Tetsuwo, Konan.
2. Stats. Recently I've seen numbers of qualifiers for ArcRevo, and then people keep assembling lists based on dan rankings.
Here is one. Fluctuations are generally pretty low from week to week.
Taokaka 160
Hakumen 156 Valkenhyne 154 Jin 153 Ragna 151 Hazama 151
Litchi 147 Carl 146 Azrael 144 Rachel 141 Noel 140 Tager 140 Bang 140 Mu 140
Platinum 139 Arakune 138 Relius 136 Nu 133 Bullet 133
Tsubaki 128 Izayoi 126 Makoto 125 Amane 123
Average of top 10 players.

Now, this isn't really subjective. But it's something else to say that this all lines up directly to the mythical 'true' tier list. How you interpret it certainly is subjective.
