Let's pretend for a moment, this has nothing to do with 'p10' - from your replies, I gather there is no love lost here, but the issue is an important one.
I remember the first time I saw my content used without my express permission in thumbnails in a way which clearly leveraged their presentation to get their surfers to cruise their realm without many 'offramps' to the copyright holder.
Some engines do a half decent job of making it easy fo their surfer to visit you if they like what they see.
Others, are shameless in hording their traffic and if they do have a link to you somewhere, it's often in a frame with them sitting on your head.
I think frames used this way are another form of hotlinking (bandwidth pirates).
If they cause you do deliver your content (and pay the bandwidth), giving you only half a screen to make your pitch this is an unfair disadvantage.
The obvious fixes are not as simple as they may seem:
Use frame busting logic in your pages? -- Maybe this is fine if you don't cater to an international audience which uses translation tools to surf your site. In my case, I get signups from surfers using translation tools (frames) and breaking out of these frames would break their experience (and my signups).
Exclude the image search bots? -- I don't know about you, but I am very wary of hoping for SE prominence on my text content if I'm telling the same owners I don't want their image bots snooping around - we know how the world turns.
What do you think about search engines encroaching the realm of using (your) 'adult images' to get traffic?
