Outsourcing Contacts

Afternoon folks,

I've spent a considerable amount of time browsing through a number of websites being sold off through popular means. I've noticed a significant amount of service providers offering Facebook likes, Twitter Followers, etc - only the work is all outsourced.

Whilst this doesn't seem uncommon any more, I'm just a little perplexed as to where the owners of these services find their outsource "contacts". Are these readily available? Can anyone stumble across this stupidly cheap outsource companies?

Cheers

Fiverr offers all these outsource jobs. Many sellers to choose from.

Maybe not as cheap, but odesk is pretty popular too.

You can find many here who can provide you Facebook likes, Twitter Followers etc. However the "contacts" are not got in few days rather it takes time to get real contacts.

Even i see more and more websites like this being sold in flippa. My question is, all these sites indicate that their website makes $1003 in 10 days and flip for more money. Wonder where are these guys getting traffic and selling their services?
