What SaaS platforms face in 2026

Trial abuse via proxy rotation

Competitors and freeloaders spin up hundreds of trial accounts using residential proxies that bypass IP-based limits. Each one burns your infrastructure and distorts your conversion metrics.

Multi-accounting with antidetect browsers

Users create multiple accounts using Kameleo, GoLogin, or AdsPower to game referral bonuses, avoid bans, or test your product for free indefinitely.

Feature scraping by competitors

Bots using clean residential IPs systematically map your UI, extract pricing, and benchmark your product — bypassing rate limits and bot detection.

Fake signups inflating metrics

Bot-generated signups make your funnel metrics meaningless, waste sales team time on fake leads, and inflate your MAU numbers.
