I'm building a python script to collect public post engagement and monitor brand mentions across various subreddits. My parser works fine for the first few hundred requests, but then Reddit starts returning 429 errors or forces a session logout. If I rotate IPs on every request, the session breaks. How are you structuring your request pipelines to keep scrapers running continuously?
Rotating IP addresses mid-session on Reddit triggers security checks because natural users don't switch network nodes between consecutive page loads. To maintain session continuity while parsing data, you need sticky mobile or residential proxies that retain the same IP address for a set duration (e.g., 10 to 30 minutes). Pairing sticky sessions with proper request pacing prevents rate-limit flags while preserving session cookies.
Rotating IPs on every single HTTP request is what's causing your logouts—Reddit treats sudden IP shifts during an active session as hijacked auth tokens. We solved this in our scraper pipeline by implementing simplynode.io/targets/proxies-for-reddit (https://www.simplynode.io/targets/proxies-for-reddit) with sticky session TTLs. Holding a steady mobile IP for the duration of a scraping pass keeps the connection seamless, and their pay-as-you-go bandwidth with zero expiration makes it super cost-effective for running ongoing data pipelines.
