The Hacker Project - a free online game

I always try to figure out new games by myself but now i really need some help.

1. When i connect (always bounced) i delete my logs. But my safety depends on how high my log deleter is. Since i just started it's not that high. So how can i really be safe if others have far better un-log programs?

2. I dont really understand the purpose of a Second Server other than backing up and keep your precious programs safe. I have read that players use them for their virii. So their Second Server IP will be in the logs somewhere instead of their Gateway-IP when collecting. But how hard is it for higher players to find the Gateway-IP. See my problem? So how or why do players use second servers.

3. Other than running a good FW protect and PW protect whats the best way of defending yourself when your attacked? What can i acspect when i come further in the game? I know about IP change but what can i do, wich programs do i need to run, to prevent an IP change or divert an attack?

4. I started a download wich took several hours. When i logged on the next day the download was not in my running programs list anymore. I searched my logs (none where modified) but couldnt find any evidence of someone deleting the download. It was a download from a secret server. When i connected to this server i couldnt find the program i was downloading previously. Could it be the server reset at night wich deleted my download?

5. What are the DON'Ts in this game. The unwritten rules. To explain, in some games you can kill steal (dealing the last damage and getting the exp while another player did all the work). It's not forbidden but you won't make friends. I don't wanna cause any troubles for others (not yet) but sometimes it feels your all alone on the net. I have read that some groups have claimed servers and that if you log on (maybe by accident) your gateway gets wiped. How do i know i tresspassed?

Thats all...for now.
Please reply to any question you have an answer for.

Thanks.
