Facebook filed an amended S-1 — the paperwork for an IPO — late on Wednesday. Our post-5pm brains are still picking through it, but the big takeaway is that Facebook estimates “false or duplicate accounts may have represented approximately 5-6%” of its monthly active users as of the end of 2011.
Facebook’s estimate is based on “an internal review of a limited sample of accounts and we apply significant judgment in making this determination, such as identifying names that appear to be fake or other behavior that appears inauthentic to the reviewers.”
The estimate could be thrown off by a number of factors, including mobile apps that automatically contact [Facebook’s] servers for regular updates with no user action involved, and this activity can cause our system to count the user” as active.
It’s an interesting tidbit, to be sure. But given the financial gymnastics in the S-1s of other recent debuts — here’s looking at you, Groupon and your sales restatements — this amendment feels a little snoozy. Still, chances are we have lots more Facebook S-1s to come before its debut. Can’t wait! -Julianne
