At the beginning of a month the system adds up to 2 invitations to each account in good standing with a ratio of 0.8 or higher that is older than 100 days and has uploaded more than 10 GB. You need not invite anybody, but you will not get more invitations unless you do. Uploaders are treated preferentially.
You may be prevented from issuing awarded invitations if you have a formal warning (red triangle), your share ratio is too low or your use of the site has been restricted.
If you wish to invite somebody, please be discreet and do not invite just anybody. You may be warned or banned if your invitees cause a problem. Please educate your invitees about good behaviour, keeping a good ratio, etc. Please check your invitee list from time to time and contact a member of the
staff if you notice anything wrong.
