Guys,Becareful when dealing with this user.He had a thread where he was seeking to buy users ID/Passport to register on ICOs.
Here's the thread link:https://bitcointalk.org/index.php?topic=2129205.0

Now he is asking for linkedin account.He will probably need access to your linkedin account to signup on an ICO.That mean you will expose all your linkedin informations to be registered on the ICO.I wouldn't take that risk for 25$ guys,Who knows for what this user will use your account or how the ICO company will deal with your personal informations...
I repeat myself Be careful.
