One of DT member or staff should leave a message in the new bounty thread of Livecoin, to warn all applicants to withdraw their applications, avatars & signatures within a fixed period, such as 72 hours. If after 72 hours, applicants won't do this, they should be tagged. Just in case there is a warning. The fixed period for them even can be expanded longer, it depends because sometimes people don't regularly log in their accounts. Anyway, I think 72-hour period is enough.
Leaving message on their bounty thread will not make any change since they have open self moderated thread. As I said they have deleted my post from their signature campaign thread. Lets wait for opinions from other DT members. Also need to note how many participant will accepted by them. Newbie account should use escrow at least. Still not confirmed if campaign manage by Livecoin themselves.
