POD Advice?

Hey everyone. Recently I have given POD a try, and have been semi successful with Redbubble. However, a few months ago I got screwed over by something. My account has been suspended for the past few months, and I have received two emails back from support. The first one stating that my account was caught in a spam filter, and was flagged as a fraudulent account, however they reassured me it would be reinstated. It still has not been. The other email said that I have broke their TOS, and to never associate with their website again. I am tired of waiting 3-4 weeks between emails, and their shoddy automated responses. With that out of the way, I have tried my luck with Teepublic, and Society6. Both of these sites are much harder to pull in traffic, as they are not as popular as Redbubble. I have posted all my designs to both of these sites, and not a single sale has been made in over a month, whereas with the Redbubble tags I have made closer to $40, just in a few weeks. Is there any way to drive traffic to my designs, without creating a website or something? Would something like Pinterest actually be effective? Thanks in advance.
