It looks like this player does not know that airbases are not allowed. If we ban him it will be useless since after the temporary ban , this player will continue doing the same since he simply does not know the rules , so if someone sees this player on server , try to explain to him please that airbases are not allowed.
If he will ignore you and will continue doing the same then report him again and i will take care of him

.
This time no action will be taken. Case solved.
