I'm always down to help people out; I usually do it via PM. Several people on this thread have gotten their pairs via my PM help, and I've gotten a pair from someone else's PM a few months ago.
Some resellers will get their hordes regardless, but it's about SPEED (not secrecy) when it comes to Roshes. The sneaker game is so ridiculous nowadays that we have to find every advantage we can to beat em to the punch. When a link gets posted, that speed advantage is taken away.
When it came to the euro sites for J's, that WAS about secrecy. After the Concord effect, it became markedly (and instantaneously) more difficult to cop releases from those euro sites. It wasn't even debatable.
Honestly if you really can't see that the link posting can potentially screw a lot of community members over, then I don't know what to tell you. This is a truism that's already been established in other forums.
You're right - it IS a community. And I'll always help community members. Not resellers and lurkers. It's just that link-posting isn't always the most effective way to help said community.
