Hello everyone, can you tell me how to read this graph? What is responsible for a different color and what does it give?https://imgur.com/a/m9wBVJw

Sorry for the stupid question. I just don't know how this system works, so I'm asking. Since if you take private CS servers as an example, there is a ban by nickname. Therefore, in order not to get blocked, I want to clarify this nuance. Since my main nickname that I'm playing with is busy, but a couple of his variations are free but are blocked. I wouldn't want to get banned out of the blue)

Hello everyone. I have such a question. If a player is in the blocking system, but his nickname is free, can I use it?

While watching the ban list, I saw some cool nicknames and as it turned out, they are free in EA. If I take a nickname that is on the ban list, I won't get banned for it, will I?
