Why Telegram Scrapers Break
In this video I show how to build a Telegram scraping setup that actually holds up — no silent crashes, no empty results, no instant rate-limits. I walk through both the public web preview path (no API keys, no phone number) and the Telethon API route, and explain which one to use depending on whether you need recent posts or full history. I break down the five real failure modes that quietly kill most scrapers: disabled previews, media-only messages, missing forwarded metadata, messy channel input, and FloodWaitError crashes. I also share how I pace requests, randomize delays, and handle rate limits gracefully so a scraping job runs for hours instead of dying in minutes. Pure public-channel work, sensible pacing, no workarounds — just a setup that holds up.
