It doesnt make sense.
Then people will create 1000 accounts and abuse 1000 times.

If you have more than one account, they can all be banned, yes. Read the ToS. Unless you are a titled player, you aren't ALLOWED to have multiple accounts.

OP was asking whether the punishment for banning previous account would carry over to new account.
Yes, it should be.
do not see why multiple accounts may be problem unless the one is not doing unfair things. even if some account is banned, how anyone knows that same person has opened new one, by another mail, username...
