You may have read the news that Ad Dynamo who is one of the Nigeria top Advertizing service provider will be switching off its ad network due to circumstances beyond their control. Ad Dynamo ads will no longer earn revenue on your website/blog from 1st July, 2015.

However, the rest of their businesses will continue as usual, so if you work with them on their Paid Content or Sponsored Tweets products you won't be affected.

If your account has been active in the past 6 months, we will pay any fees due to you, with the exception of accounts under investigation for fraud.
