I find this thread humorous for so many reasons... The first being that our big super-cool entry into the wide world of image ads seems to be somewhat scattershot campaign sold to match.com, one of the most heavily advertised sites on the web. It's a good account for Ning, because they spend a lot of money advertising, but I can see how it would be annoying to your audience. Pornographic? Oh dear. I really hope your members don't surf any newspapers (these ads are everywhere) or the gap catalog or anything like that.
Maybe it is targeted, and the word "lovers" in your network name is triggering match.com's (ahem) "insertion" into your pages. Which makes me giggle. It's one of those artificial intelligence moments that we are all getting used to, like when Facebook tries to introduce someone to their ex-wife. Sort of like how I cant understand the red type, all caps, bold, AND quotes. I don't know if this is indicating anger or love. ;)
Where is I LOVE KANNADA when we need him?
To be honest, now that they have a somewhat captive audience of hundreds of thousands of NC's and millions of users, I would expect Ning to make the advertising more and more prominent - just like Friendster, Myspace, and Facebook. Facebook has been tasteful so far, which has really helped their brand, but I have a feeling your users would be a lot less comfortable on Myspace.
I suppose the easiest way to insulate ALL of your members from this once and forever is to just buy the "ad-free" premium service... Assuming you have less than a ba-jillion users, Ning will be making a lot more off your network if you are paying $25 a month than they will on advertising anyway.
The "ad-free" premium service worked for me - I will just have to get used to paying more each month. I do not think the ads from Match.com are pornographic as much as they are spooky. There was one particular women who's looks were scary - not sure why anyone would be motivated to use Match.com to meet her!
I must say, this complaint strikes me as being both sexist and ageist. Why on earth would you assume that elderly women would have no interest in availing of the services of a dating agency? Just because they like teddy bears doesn't mean that they are senile and uninterested in sex.
I quite like teddy bears myself ; )
The only way your going to get rid of the Match.com ad is buying the premium service of removing advertisements. At this time, it has nothing to do with what the content of your site is, as I own sites on a certain culture and they run on mine. So unless I decide to pay to have them removed, or Ning decides to better match ads towards the networks content, there's really nothing anyone can do. I do agree though, they are VERY ANNOYING!
