I’m not sure that paying between 15th and 20th necessarily qualifies Fortune Affiliates as slow payers. Surely, after the first month’s payment, if you get paid every 30 days then that is just the same as with all the other affiliate programs that have a proper payout schedule.
If this thread is to be useful, it needs to be limited to programs who slow pay according to their own schedule.
ReferBingo is one – I got my March payment last week.
