88,267 accounts now, but at the time of the last Mt Gox dump there were 61,020 accounts. You telling me that only 27,247 new accounts were created over the course of approximately two years, in spite of Mt Gox proclaiming that they've had reached 1M customers back in December, 2013?
The 88,267 is accounts which still have a balance with MtGox. Someone who created an account, got verified, deposited funds, traded them, and withdrew them from the site would not show up in the list.
