 A simple Codeforces utility bot for Discord
 
+## ⚠️ Attention!
+
+As of 2025-03-09, this repository is archived and my instance of the bot is offline.
+
+Codeforces began blocking scraping since around 2024-08. This made the bot nearly useless, because most of the features rely on scraping.  
+Can the anti-scraping measures be bypassed? Perhaps, but I do not intend to work against the website.  
+There exists a Codeforces API, but it does not offer any way to access blog, comment, or submission data and is also notoriously unreliable.  
+With no other way forward, it is time to put CFSpy to rest.

 #### Who is this for?
 If you have a Discord server where you discuss [Codeforces](https://codeforces.com), you could use this bot.
