Would this "participation-meter " guarantee a quick removal of all the fake/ghost labs in the list? and this… 
“Who can use a fab lab?
Fab labs are available as a community resource, offering open access for individuals as well as scheduled access for programs”
who are these individuals? … can they be a group of students in a specific class in a specific university and no one else? or “open access to everybody”? I heard that a lot… as in public access is one of the fundementals values of the network… is it?
and to be honest, that’s pretty much the only thing I think should be considered in the accreditation process… as long as there are a few tools , people from anywhere sharing knowledge, basic electronics and maybe one or two machines. A 3d printer and a stupid plotter should be allright, there’s a lot of fun, creativity and talking that can happen with only these two machines. 2 machines, electronic and open access. that’s all a fablab need to be on the list
