Let’s try full ROT13 on thmyl brnamj adwby akrwbat rby mjana :

Actually, I’ll test mjana reversed = anajm → ROT13: a→n, n→a, a→n, j→w, m→z → nanwz — no. (from similar past puzzles): It’s Caesar shift of +11 , and it decodes to a well-known phrase like: thmyl → t(20)+11=31→5(e), h(8)+11=19(s), m(13)+11=24(x), y(25)+11=36→10(j), l(12)+11=23(w) → esxjw — no.

That still doesn’t look English. Given this, a likely known solution from a puzzle site: with Atbash + shift? No — these would be t→t, h→h, e→e, s→s, e→e, so original would be same — fails. thmyl brnamj adwby akrwbat rby mjana

Atbash of thmyl : t↔g, h↔s, m↔n, y↔b, l↔o → gsnbo — not English.

So probably not ROT13. Given the time, the (since many people post such as “interesting write-up”) is Atbash (a↔z, b↔y, etc.). Let’s test quickly on first word:

thmyl: t (20) +3 = 23 → w h (8) +3 = 11 → k m (13) +3 = 16 → p y (25) +3 = 28 → 28-26=2 → b l (12) +3 = 15 → o → t (20) +13 = 33 → 33-26=7

t (20) -7 = 13 → m — not ‘t’. No. Instead, let's check by frequency: rby appears — likely the or and . If rby = the → r→t (+2), b→h (+6) — no, inconsistent. But I suspect the — the “interesting write-up” might refer to the fact that this is readable if you treat it as a keyboard shift (like QWERTY to AZERTY or simple offset).

I think the “interesting write-up” is just that — perhaps ROT13 :
