I've been searching for a proper group buy ever since I got into online marketing but haven't had any luck. Most services provide low uptime and accounts that get exhausted too quickly. I also feel like majority of these services are reselling other group buys. I'm part of some private trackers and have had very good experience with them, communities in them are much more helpful, hit & run is prohibited, users seed their quota & follow the rules. I think this happens because they're closed to the common public and you've to get invited or pass an interview to get in. So I was wondering are there any similar private group buys? If not, why isn't anyone creating something like this?
