Mylot task is Pissing me off

I don't know what is wrong with the task people on mylot, they keep rejecting my completed tasks for flimsy reasons. At first I didn't just care but now when I think about the time and MB I waste on doing their task, I get very annoyed and something should be done to dispute this tasks. Please mylot admin and members how can I dispute my tasks. Imagine someone just rejected my task saying the reason for rejection is that the site is no longer active, wheras when I clicked on the site it was still very active. Is it fair? The person just scammed me and this is very wrong. I am not happy at all and please mylot admin should do something about this.
