This article introduces the relevant knowledge of "why the reptile agent IP is blocked". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Non-advanced proxy IP protocol.

Non-hidden proxy IP refers to transparent proxy IP and normal proxy IP. The transparent proxy IP will expose the real IP of the machine, and the Punic proxy IP will expose the proxy IP used, so that both of them will be exposed, which is easy to be restricted. High hidden agent IP is the best choice for crawler agents.

2. The IP rate of agents is low.

The more people use the proxy IP pool, the lower the rate, and it is likely that the same proxy IP will be used by many people to visit the same website, so it is easy to be restricted.

3. If there are too many requests, the crawler task is usually relatively large.

In the unit time, to complete the task on time, the request frequency is too high, it will put a lot of pressure on the target site server, easy to be limited.

4. Request regularly.

Some crawlers don't think about this, and each request takes the same amount of time, is very regular, and is easily limited. 5. There are too many requests for a single IP.

It is also easy to limit the number of requests of a single proxy IP. General websites will limit the number of times a single IP is allowed to visit within 24 hours or less, and the number of times exceeded will be limited.

5. Other reasons.

The anti-crawling strategy of each website is different, some websites are very strict, some websites are very loose, which requires crawler engineers to study and analyze and formulate corresponding crawler strategies.
