What is the "validated" field in the ERC20 metadata result object?

What does the “validated” field refer to? I cannot find any documentation on this.

Example:

{
    "address": "0xbb1ee07d6c7baeb702949904080eb61f5d5e7732",
    "name": "Dogey-Inu",
    "symbol": "DINU",
    "decimals": "18",
    "logo": null,
    "logo_hash": null,
    "thumbnail": null,
    "block_number": "12284129",
    "validated": 1,
    "created_at": "2022-01-20T10:39:55.818Z"
  }

Validated can also be null

It seems like this value refers to the validated block. It should be 1 for all the tokens.
