Multiple backlinks to same URL all from one page / one article

Do these extra links help at all? I would think not but i'm just wondering. Could this be harmful?

Say you had 4 backlinks in one PBN article all pointing to your website homepage, what happens with the other 3 after the first is accounted for? Are they ignored / do they pass any juice / could this be harmful in any way?

Thanks.

Looks spammy. I avoid it typically. Reminds me of SEO back in 2010.

Well only the first anchor text counts but you will definitely get linkjuice from the other links too (not as much as the first link though). How much linkjuice you get depends on the total amount of links website/page
