I've seen sites using in-line ads and it can look a mess? I was looking at one site and lots of the members were threatening to leave if it wasn't removed. Would you use it and why?
You can still use it, but set it to show 2-3 in-line ads only for each page, so members won't get upset. This is just my opinion.
If your visitors want it gone, i suggest listening as if enough are complaining it probably makes your site look bad
I know infolinks pretty good in this field. You can always try put it only in few pages and see the CTR results and the response from your users.
