PoH-V2 status:

PoH-V2 already using filebase to store files: https://github.com/Proof-Of-Humanity/proof-of-humanity-v2-web/blob/master/src/app/api/ipfs-upload/route.ts We don't know which bucket are we using, so I'm creating a new bucket within the main account and asking to Martin to change the env variables in netlify to point to the new poh-v2 bucket.

Curate-V2 status: As in PoH-V2, curate-v2 is already using Filebase to pin new files according to this function: https://github.com/kleros/curate-v2/blob/master/web/netlify/functions/uploadToIPFS.ts which is called in this util: https://github.com/kleros/curate-v2/blob/971bcb25d7600fceecf5a1b7415785af96fb3c5a/web/src/utils/uploadFileToIPFS.ts#L9C1-L10C1 Cheching to which bucket are we pointing. My recomendation is to use a specific bucket for curate-v2 as with poh-v2

Escrow-v2: Same situation as PoH-v2
