They haven’t. Read the article for one party I posted in Tulum. Watch the videos of everyone without masks.I don't see the point of a list either. For all we know these DJ's have provided a negative test and so have the people in the attendance, which is what we're all expecting of this summer isn't it? Like you've said if they are being allowed they are only acting on the local public health advice, same as a landlord opening his pub in an area when allowed. He's not going to stay shut on the idea that he's saving lives.
A landlord in a pub would have to follow specific guidelines if he reopened. No pre checks, tracking, hygiene or social distancing at these events
DJs are fuelling a cartel led economy, nothing to do with local health advice. Millions are dying and thousands of locals forced to work these events will also suffer.
