I want to buy VCC to make online purchases of digital goods

[outrageous]

Hi - I want to subscribe to some members-only websites. But I do not want to use my personal credit card because the site is NSFW.

The solution would be VCC.

However I already have a few VCC from Spectrocoin and Uquid and they were not accepted at the websites. This happens quite often unfortunately.

Do you have any good tips of where to get quality VCCs in an easy, fast and reliable way?

Try bitpay. https://bitpay.com/card/ this card may be what you looking for I don't understand why your others vcc ain't accepted there. Have you contacted them by email or phone ? Talk with support they may help you out with it.

The main reason why a vcc is not accepted is, the card processing company matches the issuing bank country, the card holder's country and the IP from where the card is being used. If at least two are not matching, they tend to reject the card. Trying chosing a card where all three matches, use vpn if needed, it will possibly work.
You can find a list of VCCs available and can be loaded with BTC here:
