You're asking a wrong question. The question should be can you post ads on craigslist without them being flagged or ghosted? Having multiple accounts doesn't mean you will have your ads go live every time you post them. On top of that sooner or later all your accounts will get connected and busted by their spam filters. There are videos on YT that will tell you how to post ads successfully from multiple accounts. The problem is what worked in 2015-16 may not work today at all. Try posting from one account, see if your ads stick.
