how they can know i submit with same ip ?

hi good morning,

Here an exemple look like "all day sucker but differents"

Ihave a list of 200 pages, i ping and i know with pingomatic you can ping again every 8 minuts (same page as ofdten).

but arrive a moment in stats all go down after pinging with same ip 3-4 times and clean cookies so i need to change ip or switch off computer and again "let's go for a new race"

So with all troubles with proxies and thrully i do not trust on them, how they know my ip or is it cookies ?

thanks a lot for your precious help,
have a nice day

I may be missing something but...

If you are sending them the exact same info every 8mins from another IP, they could be detecting the pattern. What are the odds that random people are repeating the same action every 8mins?

yes that is the trouble every 8 minuts same page
well get a list of 200 pages so nee to clean cookies and change ip after sending all list ??
