This can involve actions designed to manipulate clicks, impressions, or engagement metrics, ultimately leading advertisers to pay for false exposure.Common methods include click fraud, where automated bots generate fake clicks on ads, inflating traffic numbers without real interest. This misleads advertisers about the effectiveness of their campaigns and can result in financial losses.Impression fraud is another tactic, where ads are displayed on non-visited or irrelevant sites, falsely claiming views. This undermines the credibility of advertising networks and can erode trust between advertisers and platforms.Furthermore, scam projects may pay for advertising to mislead investors, promoting non-existent or fraudulent offerings.

Both advertisers and platforms must remain vigilant to ensure a fair and effective advertising ecosystem.
