(This question did have more details, and they are just commented out, but I wanted it to be anonymous).
Is okay to use remote access to help someone if they asked here?
Let me put it in the few words I can: We are not a help desk service.
just do not make it 'part of' Ask Ubuntu, don't advertise it here, don't suggest it, just keep that sort of stuff in chat and don't complain if something goes wrong. This also holds for sharing email addresses, real names, phone numbers, etc.
