f → g y → u l → ; (skip punctuation? maybe not) — not matching.
Let me try that:
Better approach: try known Atbash (reverse alphabet) or Caesar. But your letters have “shkn” — if I reverse alphabet: a↔z, b↔y… f↔u, y↔b, l↔o, t↔g, r↔i → “ubogi” no. fyltr shkn ntrw danlwd az gwgl
But actually I think it’s (each letter replaced by key immediately to its left, same row). Let me decode fully: f → g y → u l → ; (skip punctuation
f → d y → t l → k t → r r → e → “dktre” still not. Let me check “shkn”: s → a h → g k → j n → b → “agjb” — doesn’t look like English. fyltr shkn ntrw danlwd az gwgl
So maybe it’s ?
