@forestcatI won't really comment further on the scabies stuff since medical stuff event-planning since I do not have the knowledge needed for that. i just know from reading up that a scabies test is way more difficult than say a covid test. So I cannot tell you how you could prevent this stuff.
Other than that I feel kinda sorry that you have to kinda keep your guard up even at c3. But yeah I guess the organizers are either not aware this an issue or are ignoring it. I would obviously go with the first asumption for now.
One would assume though that this stuff is handled differently in a community which is filled with many marginalized people. Or people who are just different.
its good to hear that you could find people you are comfy with though.
And there are other events that are also hacker-related but have a different smaller vibe as well. I did make my mind to visit eth0 next year since it seems rather comfy tbh. And my friends will be there as well making it more comfy even. I dunno if you were around there last year but I do remember some people of CCCHH were around last year.
