As part of its quarterly earnings call, Facebook reported that the company has seen an increase in mobile use as its smartphone and tablet applications become more advanced. While this represents a strong opportunity for companies to boost social media marketing engagement, another revelation from the company sent a red flag to some. Facebook announced that it believes 8.7 percent of its accounts are fake, with people creating dummy profiles. Still, many of these “fake accounts” still have real people behind them – and the company offers access to more consumers in spite of some spam accounts. According to previous earnings reports, 8.7 percent is an increase from fake accounts documented in March, when the company said between 5 percent and 6 percent of profiles weren’t real.
