Facebook Fanpage growing exponentially.

Hi,
I'm new of the forum. I'm Italian and I saw 2 Italian fanpages growing very very fast in a short time period. I'm trying to figure out which metod they have used but no one it looks the case of the pages I'm talking about.

the first one it was just exponentially growing, every 5 minutes undreds of fans added without any posts. I saw this case a few months ago. I looked at it now and they also added posts changing the publish date. ( I guess) But I don't want to examine this case. It passed time since then.

I have a new case going on right now...

the second page has got more than 100.000 fans in just a week. they are using a website which you can see youtube videos only if you share the post on facebook (wpvideolock plugin). they also post a new link every a bounce of minutes in the facebook page. they have not so many share and likes on the links but if you go in the website they got many views and shares counted! If you also look at the engagement of the page it is also high as the likes!
How is that possible? Which metod are they using?

Thanks in advance.

Alex

Dont out peoples pages. Facebook watch here.

they are buying likes, or using fb ads to grow .

sorry, I didn'tknow about that. I edited the text. Thanks

I guess I figured it out how they are doing. They are using a script on the website that once you visit the website, for the first bounce of seconds you click on a invisible 'like' that follows the mouse cursor.

They must be getting it from like button on their any Blackhat share script something or must be doing likejacking
