Facebook likes script?

I am searching for a something like: like jacker it doesn't matter what it is, script, wordpress plugin or anything else which is free and works.

Also does the original like jack ninja support multiple facebook pages, i mean when somebody click in the site can he like multiple pages at once?

If you can add anything else that is important from your experience with like jacker or something similar it will be good.

EDIT: How many likes can you make a day safely without risking to ban your page, if i have multiple pages like 20 or so and every one of them gets lets say 100 likes a day will facebook get their attention more to me?

It doesn't support multiple pages at once, you need to change the url. If you have boosting for page likes you can set the jacker to 100% and get as many likes as you have visits.
