Public server for CS:GO, Left 4 Dead 2, CoD, Rust etc yes, but for CS 1.6 > no.
The only reason DD2 has players is because of boosting, if you're willing to install, manage and boost a server every few days per month then you're welcome to. But it's about time we accepted CS 1.6 has no future, we should stay with 2-3 servers, being the legacy/history of Ambrosia, but that's it. The community is going smaller simply because we still can't move on.
