I'm not sending any impressions as I stated above (I don't know why it would)
I don't have anything worth sending them to and if it doesn't help then what's the point?
I have heard of getting paid for them but not sure why anyone would want them since they bring no revenue.
Get banned from what?
I honestly just want to know if they are good for anything? These are just impressions not visitors.
The only site I have right now If you can call it that is www.TwilightResearch.com and all though Alexa doesn't rank it the last time I checked It was getting upwards of 100 visits per day which is plenty for someone that doesn't fool with it but maybe once per month.
How I found out it was getting visits was when I accidently changed the NS to a parking company when I switched 280 or so others. I didn't know anyone was visiting it until then.
