This major release introduces comprehensive stealth techniques and data quality improvements to address detection and data accuracy issues found in initial testing against @charlidamelio and other accounts.
Issue: Only 3 hardcoded User-Agents; fixed device fingerprints; no delays; gets blocked at scale
Solution:
User-Agent Pool: Expanded from 3 to 25+ modern agents covering:
Gaussian Delays: Implemented Box-Muller transform for realistic request timing:
Screen Size Randomization: Pool of 13 realistic device resolutions:
Browser Platform Randomization: Automatic platform detection from UA:
Timezone Randomization: Region-aware timezone pools:
Focus & Visibility States: Randomized browser states:
UA-Specific Headers: Dynamic header generation:
Per-Request User-Agent Rotation: Changed from session-level to request-level rotation
Session Rotation: Every 50 requests triggers full session refresh:
Improved X-Bogus: Enhanced stub implementation:
Issue: bio: null, bioLink: null, region: null, diggCount: 0 (likely wrong)
Solution:
Bio Extraction: Multi-path fallback logic:
userData.signature (most common field)userData.bioDescriptionuserData.descriptionBioLink Extraction: Robust URL extraction:
userData.bioLink?.link with URL validationuserData.bioLinkURL() constructorRegion Detection: Currently extracted from userData.region:
Safe Number Parsing: Context-aware validation:
val + 4294967296Engagement Rate Guards: Prevents NaN/Infinity:
followers > 0, videos > 0(avgLikesPerVideo / followers) * 10000 / 100Timestamp Validation: Date range checks:
Account Age Validation: Positive days only:
(now - createdDate) / ms_per_dayURL Validation: Strict regex to prevent injection:
new URL() constructorhttps?:// protocolsData Quality Scoring: 0-100 score based on field completeness:
Issue: No block detection; 429/403 responses not handled
Solution:
New: Username format validation and URL parsing
Username Validation:
/^[a-zA-Z0-9._]+$/@ prefix strippedURL Parsing: Supports multiple formats:
https://www.tiktok.com/@usernamehttps://m.tiktok.com/@usernamehttps://vm.tiktok.com/@username@username formatDeduplication: Set-based deduplication of usernames

Memory: Slightly higher due to larger User-Agent pool
