Yes.
It is safe to use Evaboot as we impose a daily limit on the export you can make every day.
Evaboot won't let you export more than 2500 leads per day per Sales Navigator account to make sure your Linkedin account will never be restricted or banned.
However Evaboot can't control what you do with other tools.
Hence the only rule is:
Don't use other Linkedin scraping tools the same day that you use Evaboot.
If you export 2500 leads with Evaboot then 1000 leads with another tool using the same Sales Navigator account then you will endanger your account.
If you want to export more than 2500 leads per day then you can use several Sales Navigator accounts with the same Evaboot account:
1 account = 2500 leads per day
2 accounts = 5000 leads per day
3 accounts = 7500 leads per day
etc…
