Why do you need 15 reputation to upvote?

Question

I'm still a newbie on the askubuntu site, and what I experienced is that you need a reputation of 15 to upvote. I don't understand this.

Say you see a question that you would like to see answered or a problem you have too, and you would like to upvote but you can't. There are 2 alternatives to upvoting:

• give a "me too" answer -> undesirable
• ask the same question, AND get 15 reputation for asking it (only if discovered not a duplicate?) -> undesirable

I understand that askubuntu wants quality questions and answers, but I don't see how this particular decision helps to achieve this. I would like to see this dropped, or can someone explain?

Answer 1

This seems to be answered on the main meta site:

• Why are 15 reputation points required to upvote?
