Setting up proxy rotation Python, my code keeps getting slapped

[Upside]

Alright so i tried to be smart and write my own proxy rotator in python. Using requests, threading, a list of datacenter IPs from a cheap provider. Script works fine for about 30 minutes then every single request starts getting 403s or timeouts. It's like the target site just waves a flag and says 'nah'. I'm not even hammering it, maybe 5 requests per minute per thread. So my question is, is my rotation logic just garbage or is it purely the proxy quality? I'm using a basic round-robin from a list but maybe the headers are still giving me away? I see all these fancy 'anti-detect' browsers but i just need my script to not die. Here's the core part i think is failing: i'm not changing the user agent per proxy, its the same for all sessions. Could that be the fingerprint? Also using requests.Session() for each proxy, but maybe i need to ditch sessions entirely? Would love to see how others structure their loops. Share your war stories, my keyboard is tired.

been doing this 3 years and yeah, custom rotators are tricky. probs your proxy pool is trash or they're just detecting your headers, especially if u don't change user agents. ditching sessions might help but more likely u gotta add some randomization and maybe use legit proxies or residentials, not datacenter.

 

[Glint]

yep totally, datacenter proxies get flagged quick. but do u think adding random delays or more human-like behavior could also help? sometimes just making the script less predictable makes a difference.

 

[Girder]

different angle: maybe ur not just getting flagged for proxies but ur fingerprint is still solid, like headers and UA are too uniform, try randomizing them more and ditch sessions if u want less persistence.

 

[Geode]

Careful with relying on datacenter proxies alone, they get flagged quick if not mixed with residentials or mobile proxies. Also, randomize headers and UA more, maybe add some slight delays between requests to mimic human behavior. Ditching sessions might help too, keep it stateless sometimes.

writing ur own proxy rotator isn't a bad idea but it's easy to overlook the fingerprinting aspect. ur UA and headers are still too predictable even with the round-robin and datacenter proxies are always risky. have u tried adding random delays or simulating more real user behavior?

 

[Glaze]

just my 2 cents, ur headers and UA are prob too uniform even with round-robin, try randomizing headers per request and ditch the session if it keeps fingerprinting u lol

 

[Upside]

Thanks for the quick tips yall. Yeah, I think the proxies are part of the issue, especially if they're all datacenter. I'll try randomizing UA more and ditching sessions, see if that helps. Might also add some delays or mimic more human behavior, smh.

 

[Throttle]

getting slapped even with proxy rotation? That's pretty common, honestly. You gotta go beyond just switching proxies, think about how often you're scraping, your headers, maybe even your user agents. Without mimicking real user behavior, you're just asking to get caught.

 

[Outpost]

different angle: maybe the problem isn't just proxy rotation but how you're doing the requests in general. if you keep hitting servers too fast or with obvious patterns, even the best proxies won't save you. I've seen folks throw random user agents and delay requests but still get caught because their timing is predictable. sometimes it's about how sneaky you are, not just proxy hopping.

 

[Void]

Exactly, I learned that speed and pattern matter more than just proxies. Even with fresh IPs, if you're sending requests too fast or with predictable headers, you're toast. Always randomize delays and mimic real user behavior. Stay sneaky.

 

[Bolt]

bruh, I was in your shoes once and learned the hard way that rotating proxies won't save you if you keep hitting the same URL pattern. I started randomizing my request timings and headers, and suddenly I got less slapped. little tweaks go a long way.

 

[Leverage]

tbh careful with just blaming proxies tho, I once thought the same but it was actually how I was handling cookies and headers. even with fresh proxies, I got slapped hard til I changed my request setup. sometimes it's not about the IPs at all

 

[Beacon]

this right here.

 

[Blend]

been doing this 3 years and man, I got slapped hard when I was just blindly rotating proxies without tweaking request behavior. it's not just about proxies, bruh, it's about how you mimic legit user patterns, timing, headers, cookies. if you don't mess with those, you're gonna get caught no matter what.

 

[Script]

Ever thought about using a service like BrightData or ProxyRack? They handle proxy management better than DIY scripts and can help reduce getting slapped if you set them up right. ymmv but worth a shot
