Inexplicable Facebook fans growth
A friend of mine has a small Facebook page for a workshop he organizes. Up until today he had around 250 likes, with a weekly growth of about 5 likes/week.
Today however the page likes jumped to 360 likes, so more than 100 likes in one day. He hasn't been using ads or Facebook fan growth "services" nor he posted anything special or viral. Also, from those 100 likes, most of them are surely not interested in the content of the page - because of language barriers firstly - as the page content is in Romanian and there were a lot of quite strange accounts - with no activity or no photos.
What could have caused this? Do you see anything that could threaten the activity of the page? Thanks!
