For the last month I was using HMA VPN too make multiple posts on multiple accounts. I clear my data, cookies, cache every time I log out and reset safari then change IP and open safari with a new ip and switch the craigslist account.. I have around 20 accounts. You will need a way to verify your accounts with a phone ( i use text plus ) What strange to me, is one of my accounts will allow me to have 20 LIVE Posts and another will only allow me to have 3 or 4. It's all about making unique ads that differ and not making any kind of redundancy in words and ads. Also don't just post the same spam ads in the same categories, but actually use craigslist and make posts like if you were using craigslist as a real person( post things in the community and interact). I haven't had any trouble using with craigslist however, It won't allow you access to Yelp ( a monster of its own ).. thats where an Open VPN comes in and that's what I'm currently experimenting with. Good Luck.
