I. Missing comments

https://github.com/code-423n4/2022-02-aave-lens/blob/main/contracts/libraries/InteractionLogic.sol#L44

@param _profileIdByHandleHash.The other parameters have the relevant comments attached to them.Therefore, consider adding for the aforementioned as well.

II. Zero address checks

https://github.com/code-423n4/2022-02-aave-lens/blob/main/contracts/core/CollectNFT.sol#L29

https://github.com/code-423n4/2022-02-aave-lens/blob/main/contracts/core/FollowNFT.sol#L48

To prevent accidental deployment to the
zero address and the need to redeploy the contract,add a require statement within the constructor.

https://github.com/code-423n4/2022-02-aave-lens/blob/main/contracts/core/FollowNFT.sol#L69

Prevent tokenIds from being accounted.

[Zer0dot]

First point valid, second point not valid, the standard ERC721 internal minting function checks the recipient address against the zero address.

[Zer0dot]

First point, as mentioned, is valid, but this will be changed with the fix to #70
