I plan on promoting most of the t-shirts on some facebook groups like dog lovers groups. First I'm going to join a lot of groups & post some funny dog pics & then I will post my teespring links promoting my shirt. I think there's two ways to go about this one way is to promote the t-shirts by just informing them about my new t-shirt design. Another way is to create 3-4 different designs & contact the admins of the groups & offer to split the profits 50/50 with them for promoting the t-shirts to there members. Here's some questions I have before I do all this. How many facebook groups can I safely post to in a day to keep from getting banned for posting to much & to quickly & how many hour's do I have to wait to post there again. Do I have to use a different ip address & clear all the cache & junk like cookies before I switch to a totally different facebook account & profile with a different email address. If I use the same teespring links on different facebook accounts facebook will catch on to this pretty quickly & ban me, will using bitly work for creating different types of links or are is there a better service besides bitly.
