The brackets represent who will got knocked out in each round!
[XX] - knocked out in first round of arrest/indictments.
[[XX]] - knocked out in 2nd round.
[[[XX]]] - 3rd round, etc..
It might be the reverse, however.
March Madness.
[ ] = playoff bracket chosen by gamblers
Q is asking Anons if they've made their guesses on who will get knocked out in the DS March Madness arrests/indictments and who will last until the finals.
Layers of brackets on previous posts likely represent how far they will go in the DS "playoffs."
[xx] = likely arrested/indicted first
[[xx]] = indicted in second round
[[[xx]]] = finals
Could be the reverse order.
