A website similarity scam is a scam where the website where you usually buy your supplements is a real website and is a dot com website and the fake website will have a dot biz on it and be a fake website. And they end up not selling you the supplements and instead taking the money and that of a few other people and then shutting down the website.
Modafinil XL dot com (Real with the guy in sunglasses, but on the second page of Google when it's usually on the first page): Buy Modafinil!
Tyler: *Searches up Modafinil XL.
Modafinil XL dot biz (fake with the guy in a mask, but on the first page): Buy Modafinil TM!
Tyler: I guess this is the website.
*gives money through PayPal.
*2 months later and no Modafinil.
Tyler's brother Josh: Yo Tyler, I found the REAL website. The other website was a fake website and a scam. A website similarity scam!
