Spamming is generally bad in affiliate marketing. Affiliate should make sure that they don't spam their affiliate links on any means of promotion that they want to make use of. Spamming makes some social media and even any other method that affiliate can think of, seem very ineffective. When affiliate spam, BMF won't hesitate to sanction such an affiliate with banning. But before then, there must be various warnings against such a behavior before the final banning.
