how can get banned from linkedin
LinkedIn's rules aren't as stringent as the ones we've seen on other social networks -- perhaps the B2B playground hasn't gotten quite so out of hand. You can read LinkedIn's User Agreement in full, or just browse these highlights that jump out for marketers:
1) Connecting with people you don't know. Seriously! You have to actually know the people you connect with on LinkedIn, or they can boot ya right off!
2) Posting copyrighted content to forums. Whether it's your LinkedIn Group, LinkedIn Company Page, or on LinkedIn Answers, you can't publish information that violates others' intellectual property rights. This one won't get you banned, but LinkedIn can remove the content and close your group or page. Additionally, LinkedIn will terminate the accounts of users who have been "deemed to be repeat infringers under the United States Copyright Act." You know who you are.
3) Using LinkedIn messages as an ESP. LinkedIn messages are not to be used for mass emailing. This constitutes a misuse of service, and can get you kicked off the network.
4) Putting links and email addresses where they don't belong. You get to fill out your profile however you want, as long as it's accurate. So if you put, say, a link to your blog in, oh I don't know, the 'Name' field ... you're gonna get shut down pretty fast.
5) Selling your LinkedIn presence. Built up a pretty big LinkedIn Group? It might be an asset, but you can't sell it or monetize it in any way if you want to stay on the social network.
6) Using bots to get connections, followers, or members. Just like Pinterest and some other social networks we're about to cover in this blog post, LinkedIn wants you to grow your reach organically.
7) Impersonating another company. Another familiar refrain, brands can't create a fake profile for a competitor to mess around on. You'll look stupider doing that than they will, anyway.
