I don't have a single doubt in my mind that JFB bots/hacks/cheats, however, I find the pics funny in a sense cause his post count remains the same, and the date/time posted is so far apart. Dunno, just think that even if he didnt post at all in between, the number shoulda jumped from 36 > 37 on the September post.
Either way, he's a cheater, will get caught at somepoint, and the game will be better upon his banning.
I remember Cujo pointing him out actively botting at Fafnir as a pld with a low delay dagger equiped. Not sure the specifics of how that one worked but I vaguely remember Cujo explaining it, after getting info from someone in Yoji.
/sigh Cheaters ftw...
