Using multiple smurfs on the board
If you upvote yourself with smurfs, that shows that you have no belief in your own words. You don't trust that anyone else will agree with you, so you try to make yourself feel better by making others think there are some people that do.
This does not win your arguments, only harms their validity. Using them to spam downvote someone else shows that you fear others' opinions for being right and you'd rather smear the person's reputation than actually prove they are wrong in a civil debate.
Now if you have a conversation with yourself using smurfs to actively have them agree with each other on a point, that's a new low. I don't have a degree in mental health or anything, but that seems like it could be a serious personal issue that may cause you and others problems in real life. Don't be that guy/girl. Speak with a trusted adult or counselor.
