- How can I know if there is a client specifying me as an exit node and the

That never happens so you shouldn't worry about it.
- If i found some clients trying to do something bad by using the method
mentiond in 1., how can I stop him? Is iptables or anything else can help me to block such clients?
If you fiddle with the outgoing traffic the most probable result is that you'll earn the BadExit flag. Read about it in [1] or elsewhere.
