'Camp' and 'Counselor' are Misnomers for DIY camps
My son is doing one of DIY's camps, but the folks who run this place don't really do much, other than provide access to assignments that participants do independently.
In this case, the camp subscription provides access to a Minecraft server populated by camp participants. Participants do not know the real names or ages of other members and are free to interact - positively and negatively - without guidance or oversight. The 'counselor' does not sign on to the server or participate in the activities. While particants must submit a video in which they pledge not to destroy each other's work, that is the extent of the digital agreement they make. Parents are not involved in or communicated with about any aspect of the kids' online activities.
I'm sure there are activities that kids can and should be doing on their own - drawing, for example - but being part of an online social network without adult supervision probably isn't one of them.
