It is quite common to still get blocked after using a proxy IP. It is like changing your clothes to go to a party, but the host still recognizes it at a glance and refuses to let you in. There are several reasons behind this.

First of all, it is the quality of the proxy IP. Some proxy IPs are like wearing fake brand names that are very conspicuous, and you can tell they are fake at a glance. If this IP has been used by others to do some bad things before, such as sending spam emails and frequently crawling data, then this IP is likely to be marked. 

If you use such an IP, as soon as the website checks it, you will immediately know that "there is something wrong with this person", so you will be blocked.

Then, there is the act of requesting. Even if you change to a high-quality proxy IP, if you behave like a robot, such as frequently visiting the same page in a short period of time, the website will feel that something is "off" about you. 

This is like wearing haute couture and entering a party, but as soon as you enter, you rush around and look at everyone. Such behavior will definitely attract attention, and it will not be surprising if you are asked out.

If the crawler tool or code you use forgets to simulate this information, or the simulation is not realistic enough, it will be like wearing a brand-name suit but forgetting to change shoes, and wearing slippers on your feet. Such flaws are easily discovered.

Finally, the website’s protection mechanism is also constantly being upgraded. It's like the host of a party hiring a private detective to keep an eye on guests for any unusual behavior. Today's websites, especially large websites, have various means to identify and block access to proxy IPs, so it is almost impossible to completely avoid being blocked.

Therefore, whether you use a proxy IP or you will be blocked, you need to be more careful when choosing a proxy IP.

But even so, sometimes it is inevitable that it will be blocked. At this time, you have to change the IP and try again. It's like playing a cat-and-mouse game, it requires a bit of skill and a bit of luck.

Even a high-quality proxy IP can be easily marked if you use it too frequently. It's like even if you're dressed appropriately, if you hang out in front of a restaurant all day long, it's easy to arouse suspicion. Therefore, even high-quality proxies need to be replaced in a timely manner.
