My question is, if you do something wrong with the account, the account will be auto banned.
If a user breaks the forum rules, they would get the punishment for the particular offence, which is also at the discretion of the admin or staff.
Some offences lead to a temporary ban, some to deleted posts, and some to a permanent or autoban.
This usually only applies to newbie members.
AFAIK, it can only apply to newbie members who have an activity of below 30 points. This means that a newbie who has a high activity (30+), but not enough merits to rank up to Jr. Member cannot be nuked.
