Bro, I was just coming on here to bring up that exact subject. I'm playing a league right now that is doing that. Apparently they have several leagues that they start a tournament, play their drives, then leave the league and join thier other league and play there.. Etc etc
Apparently there is some sort of top 100 group text chat that these guys all get together and coordinate with each other. I have even heard that guys are buying and selling top leagues.
I run a league that has been fighting its way in and out of the top 100 for the last half of the season.
My guys are all good dudes who play straight up with honor, but it's difficult when we are battling against these leagues who are subverting the spirit of the competition.
@RunTMC666 is right, these guys are killing the fun of league vs league and something should be done.
Maybe making it like 24 hours before a new member is eligible to play or zero points if you leave a league before the current lvl is over.
