I was on Literacy Base but stopped going there since almost two years as they do not pay. Strangely I see many users continuing to write there, comment and send messages.
I asked a question to one of those users who are regular there and came to know why they write there. The posts written there are packed with offers and referral links and those posts are shared with several social sites.
In other words the site is used as a place to advertise. Me being naive is an understatement.
Would you write at sites that do not pay, with ulterior motives?
