Today a user got suspended because caught using two accounts in a non legitimate way (voting irregularities to be more specific). The duplicate account got deleted.
After less than an hour a new question from a fresh new user came out.
Since both the topic, that it's not very common, and the (poor) question style were the same I flagged a moderator explaining my doubt about this new user being always the same person, and asking to check on him.
My flag was a while ago deemed helpful, but the new user is still there.
- My question is about what tools a moderator have to check on that?
- Was the moderator who looked at this case sure that it wasn't the same person?
- Or it's more likely that he just didn't share my doubt, and thought that there wasn't enough ground to take action?
- Could a moderator monitor this user activity to see if there might be a further development?
Edit: Obviously I'm not sure why he got suspended, but he was repeatedly asking the same question with both accounts to prevent his "main" one to get downvoted (due to lack of research, poor style, etc..).
