I know this won't make much sense, but i really need this info for a "unique" project i'm making. Suppose i have a site mySite.com and have a link trade with myTrader.com Is it possible for someone to send hits to mySite.com and while my trade script shows that the hits come from myTrader.com, in fact the hits come from another site ? I don't care at all if the spammer manages to send fake hits-in through myTrader.com in any way. Is this possible, technically impossible, hard to do...?
