I dont know, when I see the names it kind of seems unecisary. So far some people seem uncomfortable with the list. You should ask your members and let them tell you what they think, it might just be a select few who are uncomfortable with the list.
Anyways I dont want to sound like I am degrading SHOPS, I am very glad you created it and you are doing a great job with it so far. Keep up the good work.
SHOPS is new guys, of course there are going to be some things that need fixing. But ya I like the X Spammers Spammed idea. And then it wont take up much room when more people are caught.
