Our service is designed for businesses who want to use Craigslist as it is intended. We are not in the business of helping people bypass Craigslist's anti-spam policies by playing games of cat and mouse.
Craigslist Account Required
In order to post your ads, a valid Craigslist account is required. Most likely Craigslist will want to verify the account by telephone (an automated process). If you already have an account, that will be fine. If not, the service will include creating the account and having you validate that account by phone (an automated system sends you a code).
Flagging, Ghosting, and Banning
Posts can be removed if enough people "flag" your ad as inappropriate, even if it's perfectly acceptable. If enough of your ads are flagged, then Craigslist will start "ghosting" your ads. What this means is that it looks like your ad is accepted, but in reality it never appears in the listings. Furthermore, if Craigslist believes you are a spammer, then they may blacklist your IP address (the address of your computer). This means you cannot post any more ads from that computer until they remove you from the blacklist, if they ever do.
We will not put our Craigslist posting service in jeopardy by accepting clients that have had repeated problems with flagging, ghosting or blacklisting. Furthermore, you must agree not to post other Craigslist ads in the same category for which you are paying us to post. This would cause both of our ads to be flagged and subsqequently cause problems with Craigslist.
