I've never seen bulk mail limited to magazines. There is also a policy to slow walk the payment of bills. Pay on a 30-day schedule and if it goes longer and vendors complain then the problem is that they are too small for the Church's account. These policies are intended for the Church but yes, Scientologists want to read them as though they can be applied in their personal lives or as public Scientologist to the COS and it just doesn't work. Kind of like how the Doubt Formula is always supposed to result in a renewed commitment to Scientology but if you really do it correctly no sane person would.
