No shishir, it is not impossible however, it is very very difficult. Not impossible because there is no limit for posting on mylot. More over that friend is also uploading photographs also...
However, it is very very difficult because mylot pays 3 cents for the post which is graded as very good post and so rate of payment per post is low. So that friend has to post many times to earn 1$.
Not impossible because you can find many subjects on mylot on which you can post. So it is not very difficult to do quality posting on mylot.
