Whilst ultimately a kind gesture and a lovely suggestion, WLN operates on a fair chance type of system to attempt to give players even chances to play on either team. One of the perks to donating for vip or vip+ (depending on what price you'd be willing to pay in keys or even just plain cash) is to be favored to stay on one team, namely blue for jailbreak. Aside from also managing to get a position on staff, we don't currently employ alternate methods to secure a spot on a team.
If it helps at all though, if a player is manually muted or gagged (hell, even a full silence) they automatically will be made to play on red on jailbreak until their communication restriction is lifted.
tl;dr: we're not so eager to employ a mic verification plugin as we have a system set up ourselves to cover it, and donating for vip ranks will give you a better chance of staying on blu on jailbreak. You can't be fully immune, however.
