Proxy IP Collage Crawler Anti-Blocking: Collage Crawler Proxy Anti-Blocking Strategy

Why is the Collage Crawler always blocked? Here's the problem.

Those who have engaged in the data crawling of Collage know that the biggest headache is that the account is blocked. Many people think that the crawler code is not written well enough, in fact, 80% the problem is in theIP exposureThe first thing you need to do is to get on top of it. Collage's anti-crawling system is thieves, as long as the same IP is detected to operate frequently, and immediately give you a robot label.

To give a real case: a friend doing foreign trade with their own office network to catch 500 pieces of data every day, the results of the third day of the entire company's network was blacked out. Later changed to dynamic residential proxy, with different regions of the IP rotation, stable run for two months are fine.

Proxy IP anti-blocking core logic

There are three key points to remember if you want to capture data consistently over time:

1. Live Action Mode: Use a residential IP to masquerade as a real user, don't use a glance at a fake data center IP
2. Flow dispersionDon't use the same IP address to death, it's safer to change it 2-3 times per hour.
3. Behavioral simulation: Control the frequency of visits, don't neatly request them every 5 seconds!

 Dynamic Residential Proxy Example with ipipgo
import requests

proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

response = requests.get('https://linkedin.com/company/page', proxies=proxy, timeout=10)

A guide to avoiding the pitfalls from those who have been there

I've personally stepped in these potholes:

• Don't use free proxies for cheap, those IPs have been flagged for a long time.
• Don't use browser plug-in proxies, easily detected traffic characteristics
• Don't fight with CAPTCHA, pause for 1 hour and then change to a new IP to continue.

QA Time: High Frequency Questions and Answers

Q: How exactly do I choose between dynamic and static IPs?
A: short-term capture with dynamic cost savings, long-term monitoring with static more stable. Like ipipgo's static residential packages support monthly renewals, suitable for the need to continue to track the dynamics of competing scenarios.

Q: Can an account that has been blocked be saved?
A: Deactivate your current IP immediately and log in with a brand new residential IP after 48 hours. It is recommended to enable in ipipgo clientIP Cleaning Mode, automatically filter the blacklist IP.

Q: Will API extraction be a hassle?
A: Use the code template they provide to change a few parameters on the line , the measured access time is not more than 10 minutes . Support the direct generation of Python, Java and other languages to call the code.

Why ipipgo?

Three reasons why pro-testing works:

1. Residential IPs with direct carrier cooperation, pass rate 3 times higher than common agents in the market
2. Clients come withIntelligent Routingfunction that automatically selects the node with the lowest latency
3. Responding to technical problems within 5 minutes, last time I raised a work order at 2am there was actually someone on duty.

Finally, a cold knowledge: the anti-climbing system of the Collingwood every Tuesday afternoon to update the rules, remember to use ipipgo's test interface to check the quality of the IP in advance. Specific packages can be directly in their official website to find customer service to be7-Day Trial Set, new users also get a discount on their first order (don't say I said that).
