I have been unfairly treated. I spent an hour of my time to do research to answer this question, so I even missed the lecture I had that morning, because I wanted to sort this out and give a thorough answer (considering all the alternatives). After testing what clicking "Sign out of all other web sessions" under Gmail's "Last account activity" does, I needed to find out what enabling two-step verification does, so I created a new Google account and went through the process of syncing it with a computer on Backup and Sync. Not to mention testing what effects those have on being signed in to Chrome.
I felt doubtful whether the question was appropriate on Web Apps though, so I opened a meta post to discuss it. Although I thought it belonged on Information Security, the advice was that questions about Google's Backup and Sync program belong on Superuser.com, so ale flagged it for migration, and it was moved to Superuser.com.
Only four days after I posted that meta post, the question was duplicated. I couldn't flag it as a duplicate, as the duplicate was now on a different site, so I followed ale's advice and flagged it for migration to Superuser.
However, I'm posting this meta post because I think user0 didn't act ethically by answering that question. He/she is a regular user. I only follow google-drive and google-sheets questions, but user0 is very active in those questions. They surely would have seen the previous question... and possibly copied my answer, instead of flagging the question. It is not impossible that they saw my previous meta post.
What is particularly annoying is that they got 25 reputation points, whereas I got zero from my answer on the first question, but I'm the one who spent an hour doing research in order to answer the question.
If this kind of dynamic occurs on this site, my incentive to put in hard work with answering questions is slim.
