Main common reasons of LinkedIn account suspension or blocking are:
- Send too much profiles view requests to the server within limited time. For example send 100 profiles requests within 10 minute.
- Over access LinkedIn profiles per your daily/monthly limit. For premium accounts per day limit is different for each account type:
- Basic: 100 profiles daily till monthly limit ends.
- Business Plus: 350 profiles daily.
- Executive: 500 profiles daily.
- Pro: 700 profiles daily.
- Sales Navigator: 1200 profiles daily.
- Recruiter: 1800 profiles daily.
