blocks the project

I want to use the telethon library, but with your IP account immediately flies into the ban, I want to use a proxy, but my project is banned


Sorry to disappoint you, but the usage of proxies is unadvisable on Replit.
Item 24 of Section 4 of the Replit Terms of Service prohibits:

Use the Service to create a proxy with the purpose of circumventing any firewall or other access control measure

Therefore, Replit is likely to automatically block any Repl containing a proxy, and those that are not blocked automatically may be reported. This does not specifically forbid all proxies, but due to this most proxies are generally taken down.

Additionally, Replit tends to automatically kill any repls that attempt to access HTTP proxies.
