In answering a question, I noticed a related question with a very similar name and similar content, from another user. The question I answered was from an account created three days ago (RKP); the previous one was from a suspended user (Rohan). There's no bio for either of them, but the locations seem to match (my Google-Fu tells me that Vadodara and Baroda are actually the same place).
How can I (i.e., an SO user, not a mod or anything) tell if this is one user with multiple accounts? And if I suspect it, should I report it? If so, how?
Sorry to make my first Meta post about this, but I wasn't sure what to do. :o/
