2 things.
1 - no, scrapebox does not currently scrape linkedin. They are doing stuff with browsers and javascript etc.. now for google, so perhaps in the future, but they have not mentioned anything to me, although I also have no asked.
1.5 - what is it you want to scrape from linkedin? Because for some things you need to be connected to people (in some or many cases).
2- I have a lot of linkedin automation resources, because I heavily automate linkedin, including custom GPTs that will completley write posts with great hooks, CTAs, stay on point to the avatar, make images etc... GPTs that will carry on a DM conversation and guide them to your desired outcome and GPTs for commenting. These are not basic things, Ive got 25+ hours in just the GPT to write posts. I also heavily automate linkedin with software.
that said if you only want to say scrape linkedin for emails and your not actually using linkedin, none of the above is of any value and there is software you could try and use for this too.
anyway its a lot so don't want to hijack this thread. Drop me a DM and Ill see if I can point you in the right direction, just let me know more about what it is you want to accomplish.
