I am an italian guy and I am running an art contest using YOP Poll.
In one day I got 536 votes and this is good.
I have an audience of more than 3000 users and almost 4000 user in my newsletter.
Now in the contest the future winner has the double of votes of second place. So I started to check the IPs where vote come from.
Now giving a quick look all seems ip familiar (almost all italian ISP).
Is there a tool that I can use that:
1. take all my ips in input and in one shot check if they are in some blacklist and so on?
2. is able to understand if a group of ip can come from same domestic network ... probably after turning on/off the router to get a new ip.
3. is able if an IP come from a proxy server.
Another question is if YOP is able to detect IP behind a proxy and block them. I know in PHP looking at HTTP header it is possible to understand if an IP is forwarded by a proxy and find out the original IP, but I do not know if YOP implement this.
Thanks in advance for your help.
