High-level crafters beware: You get suspended if you sell to players who bought gil

[rabbitzero]

What makes you (or the Reddit poster) think that they were suspended for selling to a player who bought gil?

It seems like the player was banned and he's just guessing as to the cause...

Let's also not discount the fact that he might just be out and out lying. We only have his word that's why he was banned. Might have been botting, or doing other things to get banned. Is there a chance he got mistakenly banned? Sure. It is more probable that he's trying to deflect blame though.
