Funny you should mention these sites. Each one of these popped up overnight after I made this site. They need traffic so badly that they spam their URL into people auction questions, they have spammed our members, and they have spammed me. At least one has even prank bid over $11,000 on an item after saying he had no money (And I have proof). They are not to be supported here in any way. They spam for members and give high profile auction sites a bad name.
I do not recommend anybody join, or support these sites in any way.
It's one thing to create a site and turn it into what I have here. It's another thing to jump on board the bandwagon and spam our members to go join the other sites. That has happened, and because of this, I have no respect for the other sites.
Stick with the original and best, the one where actual high profile auction sellers post, including the most watched item of the year. And when I say "actual," I mean worldwide news, not just the minimum 1,000 hits required we have on that forum..
