Q: Why isn't my karma going up? How do I increase it?

A: You can increase your karma by

Commenting on a story (not your own)
Commenting on a blog (not your own)
When a story you wrote gains a new subscriber
When a story you wrote gains a vote
To curb behavior that goes against the spirit of why the karma system was instituted, karma will now only increase if the comments made are on different stories within a 24 hour timeframe. When 24 hours have passed since first commenting on a story, comment karma can be gained from the same stories once again. 

For example, to gain 10 points, you'll need to comment on 10 different stories in the same 24 hour time period. After 24 hours, you can comment on those stories again for karma. Maximum limits are also in place in 24 hour time intervals. The same restrictions are in place for blogs.

You can ask people to donate you some. If you have a friend here on AFF I'm sure they'll be willing to slip you some. You can also comment on blogs and fanfics but they must not be your own. Only one comment per blog and/or fanfic. When 24 hours is up, you can go again and comment on that blog and/or fanfic. You can also gain karma from gaining subscribers but that will take time and you must be patient. You can also get karma from upvotes and that too takes patience. To not make it obvious you're commenting for karma, you should skim read the chapter or blog and post a comment saying something related to what you've read so the author doesn't suspect anything.
