You hand over a lot of personal information which they can do anything with that they want. LinkedIn will target advertising at you based on the information you give them and you MUST NOT remove, block or obscure any of that advertising. So you use AdBlock? That's grounds for a legal claim against you, or being thrown off LinkedIn at the very least. In certain of the LinkedIn groups you will encounter a virulent form of xenophobic right-wing American jingoism. Do not, if you value your sanity, get drawn into any flame wars; and do not, under any circumstances, feed the trolls. Oh, and the spooks are monitoring LinkedIn. So be careful what you say. This isn't Facebook, but it has certain similarities as far as privacy goes.

LinkedIn offer to add some acquaintances. Sometimes, it offer me to add people that the only contact I had with them was an e-mail (or maybe we where going on a same website). No acquaintance shared, not form the same business or country... So my question is : how can linkedIn know that I know theses persons? I had think about it but didn't find any legal answer. So I'm just suspicious about the data buying.

i am amazed that Linkedin is still getting THE GREEN good rating? as long as you keep using THE FREE services all is good. But be warned, if you use the PREMIUM SERVICE upgrade for $30/mo you will regret it. I can't believe this site is the industry standard, used among pro recruiters and job hunters. The premium service (I used 1 mo. at $30) only offers the upgrade of (5) five In-Mails per month to a recruiter or similar. What a joke! Make sure you read the details. LI offers no phone support, the cust. svc. is horrible. Pull up reviews on any search engine and you will see the complaints. Cust. svc. takes days to reply to an email. The site itself is designed to make it extremely difficult to find any information on how to contact cust. svc. Many professional IT people can't even figure it out! This is all done on purpose to boost profits for LI. Also, there is no way to turn off AUTO-RENEW PAYMENT. This site subscribes to that ripoff strategy of hoping all will forget to turn off the auto-renew pay at 30 days. The only option offered is CANCEL premium svc., and when you do this you turn off all the benefits of the premium service? Premium svc. upgrade is a total waste of money, not to mention the 1 to 2 hours of stress you get from trying to contact cust. svc. to stop them from ripping you off. Just check out reviews on LI on your favorite search engine to confirm my story here. SHAME ON YOU LINKED IN !!!!!!!!!!!!!!!!!!!!!!!!!
