How to scrap more than 2500 profil per day with linkedin sales nav?

Hello,

How are people able to scrape thousands of profile from a single search if LinkedIn sales navigator actually shows you only 2500 profiles? I understand you can play with the filters to reduce the amount but do they really do it like that?

For example, with Vayne. io, you can scrape over 15,000 profiles per day using a single LinkedIn Sales Navigator account. How do they do it?
