Shapeshift also delisted a bunch of items because of SEC’s “Securities” decision. Im not aware if the NBT’s delisting was before or after Oct 15. But Nushare is a token that could be considered a security. I heard somewhere else that SEC has said that if the item is used in the underlying system, it may or may not be a security. Heres the decision if someone wants to read it thoroughly.

As part of our ongoing diligence to keep our services compliant with global regulations, ShapeShift has chosen to delist a few digital assets from the exchange, as they may have a risk of being classified as securities. The delisting of these assets is not a statement on whether or not the assets are in fact securities, but we want to take a conservative approach.
ShapeShift continues to review all potential new digital asset additions to evaluate their risks as securities and will not be able to make them available for exchange if they are determined as high risk assets.
We appreciate continued patronage and understanding.
