How many users have created more than one profile on SO to vote himself/herself on his/her other original profile? There are some benefits when you have more reputation and sometimes you don't want a single -1 vote on your question and answer. In this case you may have an extra account to convert that -1 vote into 0 vote and up-vote for each of your question and answer to gain reputation. I think it is not a good manner as a good developer.
Is there any way to recognize this situation? I think there should be some stats in each user's profile about how many votes are posted by each user on him/her or something like this.
So how many users have more than one profile? How to handle this situation? I have not created yet but............ I don't think so :)
