Games that don't show up in libraries

Hello guys I want to point out that not all games show up in your library. Yesterday I got blacklisted a couple of times because some people (kinda) said that I didn't activate Tryst, a developer giveaway that I won a little over two years ago. But the truth is that I did activate the game but since it was a beta it isn't in my library anymore. I'm not trying to get removed from your blacklist, if you want to remove me that's okay if you want to blacklist me now just do it. Tryst isn't the only game that doesn't show up in your library a few other examples are a Game of Dwarves, Sacred 2, The Tower, and so on. Here is a more complete list. I just want to point out that if you blacklist someone for not activating games you should check if the game wasn't a beta etc. At last I also want to point out that saying someone didn't activate a game is calling out, which isn't allowed. Thanks for your time.
