The only way you get the effort required from the community is to have a 0 tolerance policy on hacking. A good place to start is here by making an example of WLAG by removing the privilege of representing USF purely based upon the fact they were stonewall caught abusing a hack. Once that happens everyone can see that aeria means business and that there really is no margin for error when it comes to hacking.
Where is the use in banning them but still allowing them to participate in worlds? What kind of message does that send to the people of the community? As far as I'm concerned they have used up any kind of chances they had a long time ago and its time that someone in the senior management team of SF realizes that allowing the team that won the national tournament to walk all over your rules is unacceptable under any and every circumstance.
Allowing them to go to the tournament will cost them more money in the long run than this initial loss now cause the havoc these hacks are causing will not end until Aeria make some kind of statement. There won't be a community left if we create dual standards.
