How can a person's earnings decreases on mylot ?

One of the discussions you started or responded to probably got deleated. Towards the end of each month, the admin goes through and does some "quality control" as well and adjusts earnings accordingly.

Hey there! you probably made a violation or the discussion you responded to got deleted. Read the FAQs. Your discussion could have been deleted too. That's what I think why your earnings went down.

It happens all the time. myLot is continually going over the data and sometimes you will lose a penny or two here and there, and sometimes it will be a little more, but it's nothing to be worried about, just keep posting. Sometimes discussions get deleted, and that's usually the cause. When they do good analysis, sometimes you'll even get an increase. When myLot takes earnings away, they re-distribute those earnings to the rest of the membership, so it all works out.

the same happened with me too...i just now came to know that if we post to a discussion which is deleted then we face such problem...and don't know why they are still placing a discussion which does not exist anymore

That is when you responded to the invalid discussions and you posted invalid discussions too, and mylot deleted them because you never follow the rules and guidelines in posting here. Better to read guidelines before answering and starting the discussions. Coz that happened to me before too. Happy posting.

Sometimes this happens if a discussion you have created or responsed to gets deleted thus taking your earnings with it. The sole reason mylot delete discussions is because they breach some of the rules mylot have in their terms and conditions. Hope this helps enlighten you a bit more.
