A block does not indicate a technical problem. It indicates that you have a scraping strategy that resembles a bot.
IP blocks do not result from making just one request. They result from a pattern, such as sending too many requests from an IP address, using identical headers for all sessions, sending requests without pauses in between, or fingerprinting that resembles a bot’s pattern.

Why Sites Block Scrapers
Sites protect their data for a few reasons: infrastructure costs, competitive concerns, and terms of service enforcement. The detection systems they use range from simple rate limiters to full behavioral analysis tools like Cloudflare, DataDome, and PerimeterX.
Rate limiting is the most basic layer. Send more than a threshold of requests per minute from one IP and you get a 429 or a silent block. The fix is straightforward: rotate IPs and throttle your request rate. The harder problem is fingerprinting, where sites identify bot traffic based on header patterns, TLS fingerprints, and missing browser signals that real users generate.

The Three Layers That Get You Blocked
IP reputation is the first and most obvious layer. Datacenter IPs are easier to flag because they belong to known ASNs (AWS, GCP, Hetzner). Sites maintain blocklists of these ranges. If you are scraping anything beyond publicly accessible, low-protection data, residential proxies will significantly reduce your block rate. Residential IPs come from real ISPs and real devices, which makes them much harder to identify as proxy traffic.
Request timing is the third layer. Sending requests at a perfectly uniform interval is a dead giveaway. Real users are inconsistent. Add jitter to your delays — a random wait between 1 and 4 seconds is better than a fixed 2-second pause. At scale, this means building throttle logic into your concurrency manager rather than hardcoding sleep calls.

Sessions vs Per Request Rotation
Not all rotation strategies work for every target. There are two main patterns.
Per-request rotation assigns a new IP to every request. This is the right approach for high-volume price monitoring or bulk data collection where each URL is independent. The downside is that some sites flag accounts that appear to jump locations between requests.
Sticky sessions hold the same IP across a sequence of requests for a defined window (usually 1 to 30 minutes). Use this when scraping multi-page flows: login, navigate, extract. Switching IPs mid-session is a strong bot signal on session-aware platforms.
Proxyon supports both modes. You control session duration through the proxy URL parameters, so switching strategies does not require code changes beyond the proxy string itself.

Final Thoughts:
Avoiding IP bans at scale comes down to three things clean IPs, realistic headers, and unpredictable timing. Residential proxies handle the first problem. The other two are engineering decisions. If you are running market research, SEO monitoring, or any scraping workflow that hits protected targets, Proxyon gives you residential proxies from $1.75/GB with no subscription required. Deposit $5, get your proxy URLs, and start. No contracts, no KYC.
