Thanks for providing the information. The scrambled letters in a box or Human Interface Proof (HIP) is used to prevent spam computers from sending unsolicited e-mail to large numbers of recipients. Our human customers prove they are human by answering the jagged character challenge. During different times and based on different situations, you may be asked to answer several jagged character challenges. Once you have done so, the number of jagged character challenges you have to answer will decrease until it rarely occurs. Because you have correctly answered multiple jagged character challenges, I have flagged your account so that you will no longer receive them.
