How can we follow the rules if we don't know what the rules are?!

This happens too often and why we have slowed down listing new items. Suddenly we try to share and we're stopped on our tracks. We asked Poshmark what the share limits are so we can follow the rules and we were told that that information is "proprietary" basically the rules are some sort of trade secret. So how do we avoid the share limit, the punishment for breaking the rules? After all this time it still doesn't make sense. we've stopped buying for this closet and focusing on other platforms. when this closet sells out, we will close.
