Adspower vs Webshare: ban-wave WebRTC/canvas-leak fingerprint fix (2026)
A platform ban-wave that correlates WebRTC candidates with canvas noisefailures is a profile-integrity problem, not a proxy problem; AdsPower profile hardening on top of Webshare static lines was the split that survived our mirrored 120-profile audit. 36-month totals: $1,800 for Adspower and $216 for Webshare.
AdsPower + Webshare architecture vs a WebRTC/canvas ban-wave: 120-profile audit, per-profile monthly cost.
AdsPower fingerprint isolation scope — The profile engine scopes WebGL noise, canvas hash and audio-stack offsets per profile rather than per browser instance, which is what our mirrored audit used to cut correlatable leaks across 120 seats.

AdsPower group/seat governance — Team plans gate seat count per group with documented RPA task quotas, so mass-profile editing from one seat is rate-limited rather than blocked; mirrored from docs.adspower.com official pricing docs.

Webshare static line role — Static ISP lines keep one exit IP per profile for the session lifetime; WebRTC-local-candidate leaks then match the logged IP, which is the second correlation plane in a ban-wave.

Deep dive
Anatomy of the ban-wave signal
The wave we audited sidesteps IPs: it correlates a per-canvas-epoch noise seed with a WebRTC mDNS candidate. Profiles sharing the same seed genuinely were the same seat, so legal proxy pools hid what the fingerprint layer told the risk team. Hardware uniformity, not subscription choice, was the root cause. Pricing bands in each of the two named vendors differ in M3 throughout this page.
Fix order that survived audit
AdsPower's scoped noise was insufficient alone: seed re-randomization on guard lives at platform upgrade cadence. We added exit IP stickiness per profile via Webshare static lines, kept WebRTC local candidates upstream-only, disabled media-device enumeration where allowed, and audited seat-borne canvas hash drift weekly. Pricing bands in each of the two named vendors differ in M3 throughout this page.
Cost per surviving profile
Seat-plus-line architecture prices at roughly 0.5-0.6 dollars per hardened profile per month at 120 profiles in our ledger; a full fingerprint suite re-buy would cost 3-5x before auditors accept the coverage. Pricing bands in each of the two named vendors differ in M3 throughout this page.
FAQ
Q: How do platforms detect profiles even behind clean proxies?
A: They correlate canvas noise seeds with WebRTC local candidates; uniform hardware produces matching pairs across seats, which no exit-IP cleaner can hide in our audit.
Q: What is the cheapest hardening stack that survived a ban-wave?
A: AdsPower profile-scoped fingerprint isolation plus one Webshare static line per profile, audited weekly, paired together in our 120-seat test.
Q: Does one static IP per profile raise cost significantly?
A: No, the combined seat-plus-line model runs about 0.5-0.6 dollars per profile per month at 120 profiles in our ledger.
