I tried to register on Instagram. When I was trying to log in I was getting info that the account doesn't exist. When I was trying to register again I was getting info that the account exists. Finally I got info that my account was blocked for violating terms of service. But… I was never using Instagram. And I was trying to create an account like 5 minutes earlier, never used any account for anything. Weird.
They let me download backup of my data! And there are some .json files, one of them indicating that the account was created literally a few minutes earlier. And everything else is empty, setting, photos, comments, profile info. They literally blocked my account just after registration for an unknown reason, before I even logged in for first time.
@pskosinski FB and Instagram lag so much... It's not weird to me what you described.
