Alternatively, it could be : "danlwd" reversed = "dwlnad" not clear.
But “fyltr”: f → u y → b l → o t → g r → i → "ubogi" (not English). danlwd fyltr shkn. Xd Vpn
Given the second part: could be "We Use" if Caesar shift +3: X - 3 = U, d - 3 = a → "Ua" no. Instead try ROT-1: X→W, d→c, V→U, p→o, n→m → "Wc Uom" no. Alternatively, it could be : "danlwd" reversed =
I think the intended is : Atbash of danlwd = w z m o d w? Not nice. Instead try ROT-1: X→W, d→c, V→U, p→o, n→m
Better guess: "danlwd fyltr shkn" looks like someone typed with hands shifted one key right on QWERTY. Test: d→s, a→;, n→b, l→k, w→e, d→s → "sbkes" no. But maybe left shift: d→s, a→s (no).
