Telegram Smart Content Forwarder & Bot Pool Pipeline — Sender Bot

**Sender Bot** is an advanced, event-driven Telegram syndication and filtering engine written in Python with the **Telethon** MTProto framework. It autonomously monitors source channels, cleanses content, strips promotional material, and re-broadcasts messages to target channels in real time. To overcome Telegram's rigorous anti-spam policies and FloodWait limits, Sender Bot introduces an innovative **Bot Pool Architecture**. High-frequency text broadcasts are dynamically distributed across an array of bot tokens with intelligent rate-limit tracking, while a dedicated userbot session handles large media, video streams, and document payloads up to 2GB. Furthermore, it integrates an automated **VPN Configuration Extraction & Rewriter Engine** compatible with VLESS, VMess, Trojan, and Shadowsocks URI schemas. It extracts configurations, validates parameters, and rewrites the remark metadata with your target channel brand. All operational settings can be reconfigured on the fly through an **Interactive Telegram Inline Admin Panel** backed by **Dynamic Hot-Reload** without restarting the daemon.

Managing large-scale Telegram media channels and curated content hubs presents numerous challenges: • Manual Tedium: Monitoring multiple source feeds and reposting round the clock is error-prone and time-consuming. • Foreign Watermarks & Ads: Source messages routinely include competitor usernames, sponsor banners, tracking links, and promo hashtags that compromise branding. • Aggressive Rate Limits (FloodWait): Frequent broadcasting via a single bot or user account triggers severe Telegram rate penalties and account bans. • Large Media Constraints: Telegram Bot API enforces strict 50MB file thresholds, requiring user MTProto sessions for heavy media handling. • Maintenance Downtime: Modifying channel routes or keyword blacklists should not require SSH terminal logins, manual config editing, or service restarts.

Sender Bot resolves these obstacles through an enterprise-grade automated pipeline: • Distributed Bot Pool: Balances message throughput across a swarm of Bot API tokens, completely mitigating FloodWait penalties. • Hybrid Forwarding Engine: Automatically dispatches rich media and documents via the userbot session while offloading text posts to the Bot Pool. • Granular Regex Sanitizer: Cleanses messages by removing competitor handles, invitation links, hashtags, and blacklisted words, paired with file extension whitelists/blacklists. • VPN Configuration Extraction Engine: Parses VLESS, VMess, Trojan, and Shadowsocks protocols, validates schemas, and overwrites the config remark with target channel branding. • Persistent Queue & Resiliency: Persists in-flight queues to disk and leverages exponential backoff retries to guarantee zero message loss during network interruptions. • Time-Window Scheduling: Enforces customizable active hours per channel (e.g. 08:00 to 23:00) alongside randomized delays to emulate authentic human posting. • Telegram In-Chat Admin Panel: Complete remote administration through interactive inline keyboards with hot-reload capabilities for zero-downtime reconfiguration.

Constructed on asynchronous event-driven principles (Python AsyncIO & Telethon) divided into modular subsystems: - Message Monitor: Telethon-based listener that subscribes to incoming channel events and message streams. - Filtering Engine: Multi-stage pipeline evaluating content type, keyword blacklists, regex link cleaning, and file extension policies. - VPN Extraction & Remark Modifier: Specialized parser inspecting URI schemes and dynamically rewriting remarks for brand consistency. - Queue Manager & Scheduler: Per-destination persistent queues backed by disk storage with configurable active time windows and randomized pacing. - Hybrid Dispatcher: Routes text payloads to the Bot Pool Manager while streaming large documents via the MTProto user session. - Remote Admin Bot & Hot-Reload: Independent inline keyboard UI providing immediate configuration updates without stopping background workers.

• Fully automated 24/7 syndication of hundreds of messages across multiple channels. • Complete elimination of FloodWait rate restrictions through Bot Pool load balancing. • Zero-trace content cleansing removing 100% of unwanted competitor links and ads. • Zero message loss guaranteed by disk-backed persistent queueing and exponential retries. • Full operational control via Telegram mobile chat with instantaneous hot-reload.
