There is always a chance of getting restricted on LinkedIn, but you can minimize it by following some steps like
Get a LinkedIn Premium subscription like Sales Navigator.
Verify your LinkedIn profile.
Manually grow your connections to 500+.
Warm up your profile manually by being active and engaging.
Make sure your account is at least 5-6 months old before starting any automation.
Once your profile is warmed up, start automating slowly like limit it to around 10 connection requests/day and 20 messages/day max for the first 2–3 weeks. Then gradually increase the limits.
LinkedIn is less likely to restrict paid accounts, as they don’t want to lose their paying customers.
