Payment failed, Risk Payment, Unsettled: how Facebook checks a card (BIN, billing, IP), what each error means, step-by-step diagnosis, billing threshold, 8 criteria for choosing cards and a comparison of 8 virtual card services for media buying.

Dolphin Anty, Octo, AdsPower, Multilogin, GoLogin, Vision, Undetectable, Incogniton, Kameleo, MoreLogin: official prices, free plans, team features, API. What leaks in a fingerprint, which antidetect to pick for Facebook, TikTok and Google Ads, 8 mistakes that get you banned.

How mobile proxies work technically and why Facebook trusts them, three billing models (per IP, per GB, your own hardware), the "one account — one IP" rule, a pre-purchase proxy checklist, and a comparison of 12 catalog providers with prices and GEOs.

The network shows leads, the tracker shows zero. We break down 12 reasons a postback never arrives: from a lost clickid and a wrong macro to IP whitelists and duplicate filters. A step-by-step diagnostic flow to find the break in 15 minutes, and how to test a postback before sending traffic.

What a postback is in plain terms, how S2S differs from a pixel, how the clickid travels source → tracker → network, step-by-step setup, sending conversions back to Facebook via CAPI and common mistakes.

What a PWA app is, how it differs from native, why it became the standard in gambling and betting, what PWA builders cost and how to build a funnel with push and high install rate.

How mobile proxies differ from residential and datacenter ones, which type fits which task, what a good proxy costs in 2026 and how to test IP quality before buying.

What a browser fingerprint is, which parameters platforms use to link accounts — canvas, WebRTC, fonts, user-agent — and how to set up an antidetect browser with proxies properly.

Not a "top-10" list, but a scenario-based breakdown: your budget, your offers, whether you need cloaking — and which tracker actually fits you, without overpaying for features you won't use.

A complete AI creative production line: which tasks AI covers, how the "idea → generation → selection → test" pipeline works, why pure AI burns out faster than hybrids and how to avoid synthetic-content bans. With prompt examples and test structure.
