Just got this email, thought my pocket felt a bit light! Dear Publisher: A subset of our publisher base was affected by an ACRU reporting issue. This issue, a result from some recent site changes linked to registration, caused the number of active confirmed registered users (ACRUs) to be slightly under-reported on a few occasions during the February and March timeframe. The issue has now been corrected and after a full analysis, activation data has been re-calculated for this time period. You will be receiving the appropriate make good in the next payment cycle. We apologize for any inconvenience this may have caused you. Thank you for your understanding and continued support of the program. Sincerely, The ebay.com Affiliate Team
