Disable All Macros/Ghost Macro

Is there a way to prevent Macros from working?

I ask this because of several things

1. There is a Macro in my bar that a player came up with for initiative, it works for the players but I don't use it as a GM and I can't remove it from my macros.

2. Some of my players are using a second Macro, this is the problem macro. It's not in my list of Macros but it effects me as the GM.

For instance, they can see the full list of name choices below the chat box, and when they select one they aren't supposed to have access to it changes mine, THE DM, to that voice. I'm also worried this may be giving some of the players access to material they should not have access to.

This may provide some insight on how macro's works and the settings. https://wiki.roll20.net/Macros. My understanding is that a player in the game can create one either through the abilities tab on their sheet or a "global macro" that can be shown in the action bar on their screen. Unless a player has been promoted to gm or you are unintentionally giving access to global macro they shouldn't be able to affect the gm directly with the added exception if they are targeting a token in macro call, but then again that limited as well. Without knowing what the macro does its hard to say for sure. The link above should give you some basics to cover.

I'm the only Gm of the game.

So it appears in the Macros Tab between Jukebox and My Settings. So it's a global Macro? The player "wrote" the macro so it's supposed to create a dropdown menu to allow them to choose skills without clicking back to their character tab. Yet I'm seeing it, I guess they're sharing it? Are all their macros supposed to be visible to me as the GM?

Does this mean if anyone shared a macro it would appear in my global macros whether I wanted it to or not?

It sounds like either that macro or one the player isn't sharing is causing a "bug" that's allowing them to control which "As:" under the chat window the GM speaks as. It could be revealing further info that's supposed to be GM only as well.

A player cannot assign sharing settings to a macro, sheet or handout. Something odd is going on. Are you sure they have not been inadvertently promoted to GM in the player list on your game's home page? Did they ever have that status in the past?

They are not and have never been a GM for this game. They do GM another game that I was a player in, but we've never been co-GM's of the same game.

If they're not the ones sharing it then there is a macro which happens to be the one they are using that is listed in my macros, and I have no control over it.

Are you the creator of this game? 

Yep, I'm the creator. Running a module (Dragon Heist).

It isn't in any of my other created games, and I just created a fresh game to test and there were no global macros there.

Although I did discover my purchase of Dragon Heist isn't on my account now, so maybe that's causing an issue?

Have you contacted roll20 support, at team@roll20.net? This sounds like something only they can address.

I've gotten part of it fixed thanks to them.

I guess noone knows of a way to disallow macros tough.

The reason we haven't seemed to answer that directly, is because what you;ve been describing should already be disallowed. Macros have strict permissions, and a players macro is automatically limited in certain ways unless they are the GM.

Can you tell us what got fixed? What problem remains?
