I just did a random sampling of these accounts, and what's interesting is that every one of the twenty accounts I looked at had about 3-6 followers, and was following thousands of people (or it was suspended).
All their bios sound like bot-generated text, they all have suspiciously similar passwords that look auto-generated, and none of them seem to have much to say.
On a hunch, I logged in to a few of those accounts and saw that they all had messages asking them to confirm their email addresses, as they had not done so yet.
This is probably not a "leak," but some spammer's list of fake accounts.
