GM or hacker changed hired merchant titles on all 22 FMs in Mardia

As Haruna said above, I've had my store title changed without anything 'bad' in the title a couple time in the past week. I usually have B> NX or my YouTube channel in the store title and then I can see why it'd be changed but the past couple days I've just had S> Empress gear and B> Tyrant Lycaon and it still gets changed.

It's still a GM. I've had mine change before way back then for similar reasons as you. They tend to only do the major FMs, 1 and 2. Then they stop randomly.

The only reason I believe it's a GM and not a hacker is the phrase they chose is (almost) verbatim to the ones from years ago.
