How to autovote on pligg without get caught?

I created a few profiles on a pligg site only to vote my own articles but (me stupid) get caught in a couple of days, but don't want to give up with this method

can someone tell me a good method to create profiles and vote my own articles in some random way without getting caught? there is some software out there? does pligg owner see voters IP?

pls share

thankz

I guess they will see the IP and auto flag if its the same ip. So try to use proxies, if your using proxies maybe your doing it to fast (try with a interval).
