Sometimes you can get suspended with no violations at all,it depends on your answers,i know some people has been suspended with no Violations,and people have more than 50 violations and their accounts still safe.
Getting suspended depends on what kind of violations you have,for example "Adult or Harassement Contents" or other VERY bad and srious violations can lead you straight away to get suspended,,so you need to behave your self in your answers and always follow the community guidelines.
However small simple violations like "Chatting" or "Questions and Answers Formats" don't lead right away to get suspended and it would take some time. If you got a huge amount of violations (No matter what it is) in a very small time,then you have a big chance of getting suspended (For example if you got over 30 Violations in one or two hours,then you have a very BIG chance of Losing your account).
Getting violations is also a warning that your account is in danger (everyones accounts are on danger if our questions and answers violate the community guidelines)...this means "No chatting, no insulting other users, no asking questions about users.....ETC because Y!A is not a chat room
You need to put in your mind that getting suspended is permanent,you can try and send a message to Y!A asking them to appeal your account back,but it's a very risky move since 85% might decline it,but you can always give it a try
PS:VERY bad answers such as Cussing, Posting very bad pictures...ETC can lead you straight to suspended + You will lose your Acound ID as well
You have to read this Community guidelines and understand everything
