Certain advertising verticals are traditionally subject to increased scrutiny: crypto, Nutra, dating, financial services, and any related products. The reason is simple: historically, these niches have seen a high number of user complaints, questionable promises, and attempts to circumvent restrictions.
As a result, moderation becomes stricter and tolerances become lower: what "passes" in one niche may result in rejection, restrictions, or blocking in another.
This is precisely why the market is in demand for approaches that help reduce the risk of bans and restrictions through a more stable infrastructure and a sound launch strategy. At LuxAccs, for example, the focus is on renting ad accounts for various sources (Facebook*, Google, Taboola, Bing, and others) and on recommendations for reducing rejections and blocks—precisely because for many teams, sustainability is more important than a single "successful" launch.
