Summary
TLDR: Wallet developers have the right to create block lists to filter out spam NFTs and tokens, but users can reveal them if they choose to. The core network must remain permissionless.
Key Points
1. Wallet developers have the choice to institute a block list for filtering out spam NFTs and tokens in their ecosystem.
2. Users always have the ability to reveal blocked content if they choose to do so.
3. It is important for the core network to remain permissionless while still allowing for choices to be made at the wallet developer level.
