PBN or DropShipping Store ?

Hi,
I ve been scrapping expired domains for a while and I found an interesting store active since 2008, a REAL shop never spammed, with 3k Facebook pages, selling products in the surf niche..
wondering :
if I registre it and store to add it later to my PBN or even set up a whole commerce website and dropship from Chinese wholesaler..

Would I get some traffic from the page already indexed? (301 redirection or stuff...) and
how much it's worth if am planning to buy others?

Hi,
Domains who has been used this way are spammed ? bad for pbn ?

always wondering the same thing ..
