It's important that you find out what you are gaining from being here. Helping others is great, but what are you getting out of it? That seems worthwhile to know.

Also, something to keep in mind....just because the attacker is not receptive to your feedback doesn't mean the information and support is not valuable to others. Sometimes I've read some threads and have gained insight and valuable information without acknowledging it. I realize that this doesn't help the poster of that valuable information, so I will take that into consideration. Most times, it's because I don't want to get involved in the drama and become the target of attacks...I just don't need that in my life.
