Send an email to twitter that was made with the twitter account. Twitter will probably unsuspend it for you
The same happened to me two days ago. Follow the instructions when log in, they answered and activated my account again without problems.
If you guys actually ever read the complete post, you will find that the OP has already got his account activated once again but what he is asking for is whether he will be monitored by Twitter further or not.
@OP, yes, they will keep an eye on your account for a while and it might get suspended again if they see any suspicious activities going on such as mass following or mass tweeting so stay within the radar and you would be good to go.
