I found this part interesting from superstars92.
"In fact, your comment really got my attention. I don’t think a single person ever mentioned this in previous threads (I think most just assumed “colluding” meant working together), but what you are bringing up is a serious accusation. Not only is it obviously a rules violation, but do people realize how much a benefit this is? I don’t want to accuse them of anything, but your comment really got me thinking.
Not only can they submit more +EV entries (from 150 to 300) into a GPP, but the biggest benefit is a “social benefit.” Imagine having to only work on DFS every other day, do you realize how much more chill your life would be. You could be so much more productive in general, have more time to do other things (including improve DFS), and only worry about submitting every other day. This gives them a huge distinct advantage over every other person, especially other pros if they are grinding every night. There are times that like I eat a slightly late dinner, and I’m not even a max 150 every night type of guy because I’m scrambling on late news. Imagine if you did none of that because your brother took care of that for you tonight."
