Why my earning in MyLot can be decreased?? I get $0 for posting???

I can only think of 2 senario when you earn nothing for posting. 1, the comments or discussion that you have created has no value lacking response or quality. 2, the discussions or comments that you have created or responded have been deleted by the admin due to inappropriate content or violation of MyLot TOS. I couldn't think of anything else at the moment.

You must have made a discussion that violates the terms and or responded to a discussion that do the same. Either of the two, your post/s will be deleted and that will decrease your earnings as well. There are also circumstances that you have responded to a legitimate discussion but someone responded in it that violates the guidelines then there are tendency that the entire discussion could be deleted. This may not be directly your own fault but sometimes this happened.
