how should you deal with people who are frustrating? who frustrate you on purpose?

After tomorrow you won't have to worry about that anymore. 

just ignore them, in a couple of days you wont have to deal with them

I thought you meant personally, not yahoo. 

If someone is trying to frustrate you to get you angry then their end goal is to get you to react. Then your response should obviously be to not react. They'll try to increase their efforts to get the same reaction that they're looking for, and your response should be to increase your efforts to not react. By not react, I'm not meaning just sit there while they throw things around (or whatever they're doing) to get your attention. I'm meaning more...these type of people need your attention, they actively seek it out, and once they have it then they actively seek out your reactions to whatever they do next. The kind o fnot reacting that I'm meaning is more along the lines of when you notice something but you're not focusing your attention on it, or it's so dull to you that you don't react to it beyond acknowledging that it exists. They throw a fit in your face? So? You're so bored of it, and it's so unimportant to you that you move past them and keep walking. They harrass you via text/phone to get your attention to focus on them? So? Just because they want to phone doesn't mean that you care enough to pick up/respond to a text. They try to provoke you by saying that something you care about/like is bad/pathetic/whatever. So? Ok, think like that, that's fine. No matter what they think of it or say about it or you, at the end of the day their thoughts don't matter. You like it - good, continue to like it. You want to go to that thing, or do that thing - good, do it then. 

For some people you just need to let them finish their rant, then completely dismiss them and continue on with what you were going to do anyway.

Lucky you! Y!a shuts down on the 20th so you needn't be bothered much longer.

You avoid them.  So if they are on this site, you stop using it.

These people are ignorant and plot with other people against you. I'm in the perfect mood and they miss many opportunities. Of course they are not worth anything I'm living for. As bad as they make me feel, I'll rather just live on and screw them until they learn their lesson.

Not sure I understand how the other person is at fault when you are the frustrated one.  I understand getting annoyed, but frustrated? Why?  We don't need their approval; they aren't stopping us from anything. We have no need to control them, we can ignore them. Where is the frustration?

This isn't a power struggle event here.
