In FollowNFT.sol, whenever a follower is blocked by a profile and his followTokenId is unwrapped, processBlock() will mint the follow NFT to the followers address:
FollowNFT.sol#L198-L203
However, if the profile owners address isnt able to follow NFTs, such as profiles held in a secure wallet (e.g. hardware wallet or multisig), the minted follow NFT would become permanently stuck.
Consider allowing the follower to recover the NFT by himself by assigning profileIdAllowedToRecover to followerProfileId: 
FollowNFT.sol#L198-L203
