In your opinion, what are other nice revenue generators. I have been given links, but tehre are so many of these...
Honestly, you missed out big style by being banned from AdSense - they are by far the biggest and best. You could try YPN (US only), AdBrite, Bidvertiser, Clicksor or Kontera. YPN is the next best option after AdSense but it is only open to US residents.
Impressions wont get your account disabled, you are supposed to get a warning email saying you got "invalid impressions". You get your account canceled without warnings only if there are invalid (fraud) clicks on your ads units. I was working on my sites templates many times, making from 200 to 1400 reloads/impressions. Nothing never happened.
I don't think that impressions are the reason. If that was the case, Ad Revenue Sharing sites (like DP) could cause your site to be banned also, if someone (or even you) reload too many times a thread where you've made some posts.
Are you entirely sure it was the impressions because 200 impression sin't that much but the clicks......they do tend to get resally up tight about that and to a certain degreee they have a point. The trouble is that Google aren't hot on the negotiating/appeal front unless it is worth that much to go after them with a lawyer (which I guess in this case it isn't). I have had a few emails from adsense now and then and by and large they are responsive if you get back to them with a detailed rebuttal.
