Bonds are purely to stop scammers. When the original SR launched a public drug marketplace was just an idea. Now its well established. If it was open season to any vendor, it would be a scammer paradise. DPR has told me specifically that he would prefer to have 100 quality vendors than 1000 scammy vendors. If a vendor cant afford the bond, which they get returned to them after a short period, then they probably wont make a very good vendor
