Facebook proudly announced that it had – as it believed – put an end to the nefarious practices the company described as “sophisticated” and the “coordinated operation” that has targeted Facebook with spam over the past six months.
In a blog article, the Facebook security team explained how “fake likes” came from accounts in “Bangladesh, Indonesia, Saudi Arabia and a number of other countries”. Also, the fraudulent accounts seem very clever compared to the usual accounts of spam, as they were using a proxy to disguise that they were not managed centrally by certain parties.
With regard to size, Facebook did not come up with accurate figures, but only gave approximate numbers, as the company said
“As we remove the rest of the fake likes, we expect that 99% of pages affected by more than 10,000 likes will see a decrease of less than 3%.”
