They MAY incur a squelch due to players colluding to abuse the RCR to impose their own brand of vigilante justice. That does not mean the squelch was warranted.
They MAY even incur a silence if they actually committed a violation.
The final decision is up to Blizzard.
Hopefully Blizzard lowers the hammer on those contributing to unwarranted squelches when those squelches are overturned.
