It has been suggested to add a command to prevent from triggering gestures, like @gesture=n. Or we could go a little finer and restrict only sounds or anims or chat. Like @gesturesound=n, @gestureanim=n and @gesturechat=n respectively.
Personally I think such commands would be a bit heavy to the user, but what do you think ?
I think it's long overdue, how is this worse than blocking chat and inventory to prevent a user from saying silly things while playing silly animations and abrasive sounds ?
