The invite system is a friendly way to grow at a healthy rate, while reducing spam without charging for accounts.
It is also invaluable in conflict resolution. If an account or series of accounts is misbehaving, it will be much easier to identify technical API abuses like spam based on their invite patterns.
And in the case of a more subjective moral abuse, it will still be helpful; we will be able to approach those who invited the user, who will be able to act as an ambassador between pnut.io, those abused, and the accused.
You are inextricably related to those you invite, so do not invite anonymously unless you're comfortable doing so. But by the same token, we will not move quickly to censure accounts related to abusive accounts.
Invites only accrue on their own each time that you go to the Invites page in your account. They will only increase by one (1), 24 hours after your most recent invite creation or use.
You may have up to seven (7) invites at a time.
How to Give Them Away
You may give a friend an invite directly by giving them the code and sending them to https://pnut.io/invite, or by appending the code to that link yourself, and giving the whole link to them.
Alternatively, you can have pnut.io E-mail them the code directly... Just be sure they know to check their spam if it doesn't arrive within a couple minutes!
If you have pnut.io E-mail them, that code will be tied to that E-mail address for 24 hours, and cannot be used by anyone else.
