It's not detected. Probably just a delayed ban.
It would be a delayed ban had I ever botted on this account, on this computer or on this IP ever before. This was the first time I ever botted on Runescape since its inception.
More to support the fact I never botted, it was just a 2 day ban.
EDIT: Also I'm not pissed or anything, to be fair I don't care, I botted I deserved it. Just letting YOU know that, since I literally only ever used this bot on my main, lvl 130 account, created in 2005, there might be something on your script that is probably raising flags at Jagex, since this was the only bot I used. I watched it for a long while and it behaved pretty well, aside from those 2 instances of AFK'ing after teleporting back to Edgeville.
