How do you detect fraud aside from checking IPs and cookies?

I got a hunch that someone created another account to vote for himself but I don't have any actual proof. What I've been using so far is checking the mysql database for identical IPs and cookies. In this case, that doesn't help.

What do you do to detect cheaters?

You've just found out that one of your users created another account to vote for his own questions and answers. After checking some data you realized the two accounts do belong to the same person.

Aside from removing the irregular reputation points, how would you punish the user?

Please describe measures that would discourage future rule violations but still encourage the user to continue contributing.

How to prevent specific fraud by anonymous = registered user?

I know that sounds a bit complicated, so I give you an example:

1. User asks anonymously.

2. Same user logs in afterwards, and answers the question of his own.

3. User logs out and clicks (in role of anonymous again) on best-answer for himself to receive best-answer-points.

Yes, something like this happens if you award users monthly regarding their points :)

Note: I disabled the option that users can answer their own questions! This was necessary to prevent abuse of the point system in the first place.

So any idea how to prevent this little fraud (by IP)?
