I just got an email from Bet-at-Home affiliates:
Dear Affiliate,
We regret to inform you today that, due to strategic reasons, we decided to close the Serbian market. Therefore, starting on 09 December 2019, we will no longer accept customers from Serbia. Further, no commission will be calculated for existing betting accounts from Serbia after betting accounts are closed.
We ask all our affiliates, who are and have been advertising for us in this market, to remove the bet-at-home.com advertising material from their website or other advertising channels as well as to change banners and tracking links if these target customers from Serbia with immediate effect.
