I signed up for Instagram and it said I already had an account with that email address. I didn't remember signing up but thought maybe I had done it a while ago. I reset my password and logged in.
It turned out someone else had signed up using my Gmail address. They had like 2 or 3 pictures posted. I wasn't really sure what to do since it was my email address they used (its a @gmail.com - I get a decent amount of email for people with my name).
The problem is that they linked their Facebook account to Instagram. I also linked my Facebook account. I get notifications of "my" Facebook friends joining Instagram but it's this other person's Facebook account. In the Instagram app, it only shows my Facebook as a linked account. How can I get this other Facebook account detached from my Instagram account?
