Are redirect followed?

From main/docs/operations.md, I found this extremely interesting:

3330 unique two-label .onion domains were configured from 26937 unique sites. 13956 of those unique sites have the same Onion-Location configuration as Twitter, which likely means that they copied some of their HTML attributes.

I wondered if these sites were clones/phishing attempts of Twitter. So, I tried to open a couple and I got redirected to https://x.com/someusername.

I had already seen this pattern: some people use a subdomain to redirect to their Twitter/X account. So, is the scraper following these redirects and then associating them to the original URL?

If so, personally I think these cases should be ignored instead (or considered only if there's also an explicit Onion-Location header).
