How many subscriptions off one debit card?

I'm thinking of setting up a gold farming business, my computer has an i3 processor and can handle 5 powerbot accounts and my perfect fighter on nexus...

I'm wondering how many subscriptions you're allowed off one card then?

Currently I have 2

Also any advice on the best p2p gold farming bots please? Exc. sorc garden and flax spinning

Thanks

 

For a debit/credit card im pretty sure its 3 per 30 days

 

Jnigss is correct, it's 3 accounts per card.

 

too bad powerbot doesnt work lol. use sorc garden best gold farming bot

 

Thanks for the help
