Ability to filter out content as gateway operator

[dmtrjsg]

• Create a configuration file that lists blocked:
  • Video IDs
  • Data object IDs
  • (In the future, Comprehensive category filtering #3004) Category IDs
• Make the app not show blocked things:
  • For videos, we should have a single function that creates shared filtering paramaters for all video queries. So this should return something like:

{
  where: {
    isCensored_eq: false,
    isPublic_eq: true,
    // ...
    NOT: [
        id_in: [] // list of IDs from the config,
        category: {
           id_in: [] // list of filtered categories IDs
        }
    ]
  }
}

• Make sure NFTs follow the same filtering options as videos

---

Once content is reported as malicious/ not fitting content policy and this flag is captured, we need an ability to filter this content out. Based on list of video IDs, these would be hidden from gateway.

• Include separate resource blacklist (URLs & data objects)
  Apply same logic to NFTs wrt content curation as for videos
