In the past sites used perfect money so much because it was the only alternative to liberty reserve, nowadays there is IOMoney and Yandex and WebMoney and Advcash and Payeer all these alternatives to PerfectMoney.We can only be able to make use of these payments methods when there is anything available or if there is need. I know of perfect money very well but I haven't used it before because I don't have it needs now.
