Wait, maybe "30lcpox" is a placeholder or a generated code. Need to make sure the article is informative but not based on false premises. Also, check if there's any public information about Bitly's custom short domains. Bitly allows users to create custom domains, so "30lcpox.bitly" might be an example. But the user wrote "bitly 30lcpox" as if it's a single link. Maybe it's "bit.ly/30lcpox" which is a valid short link format.
