anyone know why mylot would ..."redraw" a user's earnings?

maybe because of low quality contents..

It is possible that one (or more) of the discussions you responded or issued were deleted by the administrators for not following the guidelines. If that's the case, your response was also deleted and the earning you received from it would be withdrew from your account.

I'm not really sure. Unless you got a negitive response. I would be upset myself about this.

It could really be that some of the posts you either started or responded has been deleted, as they could've accidentally violated a discussion. I haven't experienced this deductions on my earnings, but I do get to receive additional cents even right before the daily updates on our earnings. The reason for that could be, the admin computes these earnings and give them to those who they believe deserves it..

I just starting using mylot,but I just read something about the payout going down due to high site traffic and volume[members] but not sure how long ago these adjustments were made.Have you tried contacting them about it?
