renewing my IP, is there a way?

Not for this site. But I am having issues with a venue that I use for advertising. Craigslist.
For some reason I have been getting flagged a lot and now many of my postings are deleted right away.
While it shouldn't be a big deal the craigslist ads bring in an extra revenue of about $1200 a week. So I don't want to stop. What it is, is that I am posting in items for sale, when I do a service instead. Which I get is wrong fro craigslit nerds. But my message is "don't buy used junk fix your equipment for much less". I'm looking to save the consumer money and if I can offer you a service for much cheaper as I don't pay the higher advertisement rates for those jobs, then so be it.

So anyway. I guess that makes me a spammer. I run one ad a day, many in my field run 3-5 a day.
I am also licensed and insured, while mst who advertise are not (I'm a cold caller).

So I realize my errors and how to not upset the flaggers. But now my IP is tarnished. I tried to sell a truck for a friend today and the posting was taken down before it posted.
Now I can go without craigslist, but I really do feel that I am posting in the proper category.
There is no service category for my field.

I have no ads up now, as we are closed until the 6th. But I want to start back up. The extra revenue has been nice. I get more calls from Craigslist than I get from all my print advertising combined.

(Google still gives the most, and is worth it)
