Yes, and they're all playing custom weapon servers. I am not exaggerating, the custom weapon servers are pretty much the majority at this point and the regular base game is pretty much exclusive to VaultF4 servers. These servers are pretty much all terrible.
Speaking of VaultF4, their
ban page proudly lists ~5.4k bans. It is quite unclear what is the exact timeline for these bans but in
2022 (earliest archive.org snapshot I could find) they were hovering around ~2.8k. This seems like a lot for a mod that used to hover around 200-300 active daily players before being published on Steam. There was also some rumor that they had to mass unban people at some point because they ran out players but I haven't managed to find any details about that so far.
