I beg to differ. Sorry, I don't believe it, at least not what you describe. I, just this past few minutes, just posted two different items on two different Craigslists, in two different states, just to see if I could.
I could. I did. You are wrong.
And the answer to your question, can you make your IP appear different, I would say not. You might be able to hide your location using a website that allows "
anomymous surfing" but that might not be what you think it is.
OH!! and as a further test, I just now posted to the Austin Craigslist too. So that is 3 different cities that I just posted. Need further proof?
