I just declined few tasks from my other sponsor. I am so busy and their system is quite time consuming. Creating 3 links with appropriate anchor text just consume my time so much plus, they require quite long article for each post.
This is the reason why I am more comfortable accepting jobs from my newest sponsor. Their system is very easy and fast. All I have to do is copy and past the link with anchor text and creating a personalized article for the products or services.
