What is the reason for this report?

Greetings,

Please, i need help.

I have an site where anyone can upload any video file, and I’m in trouble because the site are getting uploads with ilegal content. Everytime when i delete the video, i also ban the IP of uploader using the command:

sudo iptables -A INPUT -s IP -j DROP

But it just ban for awhile. When i retrieve the list of banned ips, the ips from the past is gone.

And I’m sure for those who are doing this is behind of proxy sites. I don’t know what i should do. Maybe is time to close my site. It was going too well. :(

When you restart the server, your Iptables rules will be gone. You can use iptables-persistent to save iptable rules. To install iptables-persistent use the command below.

sudo apt-get update
sudo apt-get install iptables-persistent

When you make a change to iptables, run the following command to save it:

sudo invoke-rc.d iptables-persistent save
