Unlocking service threatens to blacklist my phones....any advice?

[CarrierUnlock]

I'm not saying they're certainly able. The people who would know best are the unlockers here. There's the thread with one giving away unlocks. You should ask him about what all is possible. He would be a better source than I. But, it's only rational to me that if they can modify the status in one way, their hack would modify it in others as well.

Can't really do much, but I highly doubt they will have them blacklisted unless the said unlocker works for said original carriers which I highly doubt as well. Even if they did blacklisting that many phone would look highly suspicious to their employer sending red flags.
