If you automate any action on LinkedIn you risk bans or suspensions, simple as. So the question isn't yes versus no, it's very likely versus very unlikely. If you use a tool like HeyReach that doesn't resell accounts or do anything else other than automating the sending of connection requests and messages, and the rotation of those action across accounts you already own, and you do so at a per account volume that complies with whatever limits your LinkedIn account allows, you will be fine. And even if you do something by accident for long enough that you're not fine and you're account gets temporarily suspended, you will get your account back easily enough by just asking LinkedIn. Scraping data is the main thing they actually ban people for. Hope that helps brotha
