Thanks for you kind words @DarthCoin :blush:

In that case I don't think they're anchor outputs. The 330 sats for anchors comes from the fact that it's the dust limit for this kind of output (i.e. the smallest standard amount). Here, they use the same amount to ensure standardness of their transaction, but from the look of it I'd wager they're encoding arbitrary data into the addresses (thus making the output unspendable).
