On my own research, you are "safer" if you never allow the company to pay for premium options, you had the LN account prior to employment, and honor your non-compete post-employment.
All very tricky. I no longer use my LN for staffing to avoid this. http://takethisjobnshoveitblog.com/2010/06/01/employee-sued-...
http://dailyblogma.com/featured/employers-battle-workers-lin... In Minnesota, the IT staffing firm TEKsystems Inc. is suing three former employees and their new employer for allegedly violating non-competition, non-solicitation and non-disclosure agreements. What did the employees do? They continued to use their LinkedIn accounts, which they had set up while working at TEKsystems, after they had left the company. The lawsuit alleges the employees used LinkedIn to communicate with TEKsystems clients and contractors in violation of their departure agreements.

A former Sr contract recruiter with Microsoft was told she had to give up her LN account by their HR department (cannot find at the moment) after leaving she told them no, given she already had the LN account.
