I need to include more accounts to be followed

This help article only applies to the iOS app and not the web picker.

To minimize abuse and continue to offer this service free, we limit the number of accounts we validate (in addition to yours) to be followed to 3 (4 total, including yours).

But this doesn't mean you're limited to using 4 accounts in your giveaway.

If your giveaway includes more than 4 accounts, include all of the accounts in your ruled. Our app will only check for the 4 when picking a winner, but this acts as a spot check because if someone followed the 4 accounts checked, they likely followed the other accounts as well.
