I found very hard to post on craigslist in bulk. Need to use proxies and PVA account in order to set up bulk accounts. If you post 2 ads in 24 hours then this is very high chance to get banned from Craiglist. My ads won’t show sometimes because of doing bulk.
What is your question then? Are you trying to find a way to make more posts on Craigslist ? Yes, you will get banned if they find you making too many ads within the same day. You could consider hiring an affiliate or two who can post for you and receive a small commission for their time .
