AdXXX is a long-running adult-specialist ad network founded around 2006 with reach across 180+ countries. It deals in standard display banners, popunders, native, and video, operating primarily on a CPM model. The publisher pool is adult-exclusive, which means inventory is contextually on-target for adult advertisers without needing to filter out mainstream placements that don't convert.

Volume is in the hundreds of millions of daily impressions - smaller than the largest DSP players, which means competition for inventory can be lighter. That is useful for advertisers who want to test budgets without immediately being outbid by deep-pocketed performance buyers. Payment options include PayPal, Paxum, WebMoney, and wire, with multiple currency options.

Best for advertisers wanting a straightforward adult-only CPM buy with low minimum deposits and no mainstream traffic in the mix.
