Avito_fake_checker is a free Chrome extension developed by arhipov.daniel that helps users identify counterfeit listings on Avito, a popular online marketplace. This extension analyzes the text of each listing and detects the presence of specific keywords that are often associated with counterfeit products.

When the extension identifies these keywords, it displays an icon with the label "Original ", "Counterfeit ", or "Check " next to the listing's photo. The "Check" label appears when the text analysis cannot definitively determine if the product is original or counterfeit, but there are suspicious keywords present. If no label appears, it means that the extension couldn't find any relevant keywords, and users should draw their own conclusions.

It is important to note that the "Original" label does not guarantee that the product is 100% genuine. It simply indicates that the listing closely matches the typical description of an original product.

Please note that the extension only works on individual listing pages and not on the listing's overview page. This limitation is due to Avito's IP blocking policy, which restricts excessive consecutive requests from the same IP address, making it impossible to retrieve the text of multiple listings from the overview page.
