25 pages of links/pictures. Unless you've got a photographic memory and a penchant for zero-feedback, only registered a week ago, kind of adultwork profiles, I'm not sure how it really helps.
I'm going to assume for the following reasons
girls switch profiles but use same images
some do bb then decide to hide it but still offer it
some offer it on the side
as for dead links - covid is one reason, natural wastage is another, we'll see more of it as the brexit ee visa thing kicks in, with more turn over more accounts will close and re-open when they return
photos/pictures are useful to see if the account may have been sold on, that may also account for likes list changes
