-1 - Other third-party clients send the IDENTIFY message that bots use which makes Discord more likely to think you are selfbotting or spamming. However, Discord still loves to ban people's accounts for no good reason, even users of the official clients. If you want to be really careful avoid joining servers really fast or cold DMing people.  
-2 - Getting emojis to function properly on GTK is still something I've yet to figure out ([#5](../../issues/5)). Unicode emojis are manually searched for and replaced in several places as opposed to allowing GTK to figure it out since GTK's way of doing it doesn't work very well.  
+1 - Abaddon tries its best to make Discord think it's a legitimate web client. Some of the things done to do this include: using a browser user agent, sending the same IDENTIFY message that the official web client does, using API v9 endpoints in all cases, and not using endpoints the web client does not normally use. There are still a few smaller inconsistencies, however. For example the web client sends lots of telemetry via the `/science` endpoint (uBlock origin stops this) as well as in the headers of all requests. **In any case,** you should use an official client for joining servers, sending new DMs, or managing your friends list if you are afraid of being caught in Discord's spam filters (unlikely).
+
+2 - Unicode emojis are substituted manually as opposed to rendered by GTK on non-Windows platforms. This can be changed with the `stock_emojis` setting as shown at the bottom of this README. A CBDT-based font using Twemoji is provided to allow GTK to render emojis natively on Windows.
+
+3 - There are some inconsistencies with thread state that might be encountered in some more uncommon cases, but they are the result of fundamental issues with Discord's thread implementation.
