1. they have no relevant ads to post on your site;
2. they cannot (or have not) determine what ads should be posted on your site;
Even if you filter all the charity ads, it is likely you would get a big blank white box (or whatever background color you selected) in its place.

The charity ads will also appear on a page untill googlebot crawls the page and determines what ads may be relevant to that page. Even if a page has already been crawled and indexed, you will often have to wait for a "revisit" by the bot before it stops showing charity ads.
I would like to think that this is google's way of "giving something back", but i don't know.
If you really don't like charity you should consider looking for questions and answers in a paid forum.
I've noticed now that all my ads seem to be the same now. I have all different types of articles and usually it changes a little for each article. Now it all just seems to be same. I'm going to try unbanning charity and see what happens.
