Stop comment abuse

Wanted to let you know that my posts were deleted thanks to some flags inappropriate from someone who calls themselves Libi.  We were having a discussion on the Barbara Boxer Water Shortage Board and all of a sudden she was spouting off a bunch of stuff that was not true.  I ask her for clarification and she not only deleted her posts she flagged mine and others as well and had most of the comments deleted.  I understand that she deleted Jeramiah's comments as well and that he reported it to you.  What can you do about this abuse?
