People Automatically like a Facebook Page?

[allen]

There is a friend of mine he knows some trick or something, that automatically brings random people to like the page.

I and him created a Football related page, for few weeks we only had like 62 likes, then he did something, that within 5 days the likes increased to 1320, then I realised non of them are actually Football fans and some of people even disliked the page (only few like 3), But they are Real people.

Can some one tell me what the trick or what that thing is/
