What's the Best Way to Check Proxies for Reliability and Speed? or How Do You Check Proxies to Ensure

Here’s my lazy method:

- Paste proxies into ProxyCheck.io.
- Filter by "last checked <5 mins ago" and speed <1000ms.
- Done.

For scripts, I add retries. Sometimes a proxy just hiccups.

Also, avoid proxies from shady forums. They’re 99% dead or honeypots.
