When we copy an post to bitcointalk ; will i get banned from it? What are the things that can make me banned from bitcointalk? If a person get banned from bitcointalk can they be able to use their account again? What are the bitcointalk basic rules?

You'll get banned for copy pasting replies. There are 2 kinds of bans; temporary which be lifted after some days/weeks (so that means you can use your account again), and permanent which is self explanatory.

Nuh uh. You can get banned with 1 copy paste. Although sometimes the mods might be nice and give you a warning first.
