This question already has an answer here:
- Can I create two accounts? 1 answer
I provided an answer to a question that was later put on hold. While the question was on hold, a member commented on my answer along the lines of 'That's not what I [my emph.] asked'.
The commenter was not the same member who had posted the question, the usernames and profiles were very different, so it seemed odd for the commenter to comment in the first person.
Minutes later I wanted to ask (by comment) whether the commenter and OP were by any chance the same person but the comment had disappeared.
Although my evidence isn't very strong, I suspect sock puppetry at play here.
