Facebook Inc on Thursday took down hundreds of Instagram accounts that were hacked and sold for their high-value usernames, including the accounts of people behind this activity.
A Facebook spokeswoman said the people engaged in this rule-breaking practice were well-known figures in a community known as the OGUsers, who trade desirable usernames for popular websites from Twitter Inc to Netflix for money and clout.
The usernames, which can sell for tens of thousands of dollars, are often short words prized for their scarcity, like @food or @snow. Social media companies including Facebook-owned Instagram have rules against the sale of accounts.
The people accused of participating in a major Twitter hack last year, when a slew of VIP accounts were hijacked, also had ties to this practice and the online OGUsers forum.
It was the first time Facebook had shared its enforcement actions about this activity, though it said it had been removing accounts for this practice on an ongoing basis.
Twitter Inc and the short-video app TikTok also said they had recently taken action against OGUsers for breaking their rules.
An administrator for the OGUsers forum previously said the site bans trading accounts acquired through hacking.
Twitter also permanently suspended a number of accounts from the OGUsers network under its rules against platform manipulation and spam, according to a spokesman. A TikTok spokeswoman said it had recently reclaimed a number of usernames that OGUsers had registered with the aim of profiting from the sale.
