----- As one idea. I think it is very convenient when bitcash or webmoney can be used to settle VPN though the introduction seems to be difficult. It is not possible to buy it at less than age of 20 if it is bitcashEX (It has the deterrent even if it is on the polite fiction) Netridecash cannot be bought at less than age of 20. If a young person is ruining it, ruining might be decreased in some measure.
