Could it be ?
Could it be a well-known phrase from an article? “Danlwd” might be a person's name scrambled (e.g., “Dawson”?)
Given the phrase length: danlwd fyltr shkn qwy tap wy py an danlwd fyltr shkn qwy tap wy py an
danlwd ROT13 = qnayjq (no) fyltr ROT13 = sl yge — not good.
Given the time, I suspect this is a :
Try: d left = s , a left = (nothing) — maybe a left is ' ? So maybe not.
Given the pattern, I notice “tap wy py an” — if I reverse each word: tap rev = pat wy rev = yw — not right. Could it be
But also: looks like “tap we by an” if wy = we, py = by? But in some shift, w = t , y = h , then “wy” = “th” — possible.
