Internal redirecting link?
As in, the backlink is followed but goes through a redirect to get to your page?
A 301 will still pass all link juice, minus a few drips in the process, to your website. But if the link goes to a redirect link, then the link juice will be from whatever authority that URL has rather than the URL of the page with your link.
e.g.
Profile > Redirect Link > Your page
So any link juice from the 301 will be from that middleman there (which might be of lower quality), rather than directly from the profile. It will also take a few crawls for Google to recognise your page as being the destination that should be "credited".
If it's a 302, then it won't pass any link juice.
