Adcenter click fraud????? Anyone????

So I'm dropping serious $$ amongst several engines; and lately I've been noticing alot of fake leads, bullshit submissions, etc. through Adcenter. Is anyone else generating leads and having this problem? Last week I revised my forms saying "Hey dick, you will be called - don't submit bullshit" (along those lines); but still...

I almost feel that (a) Microsoft is doing it to line their pockets, but why would multi-billion dollar company do this? I thought only tier 2+ engines did this, or (b) maybe the people running MS ads on their own financial sites are using bots/proxies/etc to click and fill out bs information to get paid?

....The landing pages are tits, my ads are targeted and everything flows accordingly. I was just wondering if anyone else was having this problem, especially in the finance market.

I can only say that these are bots. Why all the BS information then, right?

Are you running on their search engine only, or using their syndicated search partners as well (still talking search here, not content). If so, then yes you may be having problems - especially if you're running outside the US. Yahoo had some really crappy traffic under their search partners. Cut it down to yahoo/bing only and you should see those disappear.
