Then you will be fine as long as you reported it to google. They are well aware of people click bombing. What usually happens here is if there is click bombing activity on your account they will roll back the clicks and give those ip's 0 weight when clicking on your ads in the future.
A good indication that your account has been flagged for click bombing is when you see your account numbers fluctuate by the hour or every 15 mins
As long as you are following the google adsense TOS and informed them of the issue you WON'T get banned (regardless of what other people say)
It might be different for new accounts but I had this problem a few times and my adsense account is 6 years old. I seen my earnings jump 1000$ or more in a day and looked at the CTR and it was 35% when the average is 4-7%. Wrote them, weird fluctuations every day and a lower than average finalized earnings for the month but I always got my deposits and then the issue went away.
Good money you are making there but I really don't think you will have an issue as long as you are genuine to the TOS and you never had your account for like 2 months or something.
For perspective (From google adsense toolbar):
