Am I shadow banned or just broken game?

Okay, so, I don't have images, because I uninstalled contractors after having this issue for about 4 years now, but here's the rundown:

At first, it was running perfectly fine, played a few zombies matches, halo mod, TF2 as well.

Then my game just.. shat itself. completely. corrupted textures, couldn't connect to anything, the entire game was broken.

Factory reset, nothing, got a Q3 a year or two later, nothing, recently tried again after deleting all its data through settings, it's not corrupted anymore, but it doesn't connect to voice chat or online services even remotely, acting like I have no wifi.
