Schema.org tricking and duplicate content across domains

[Sved]

I've found the following abuse, and Im curious what could I do about it.

Basically the scheme is:

1. own some content only once (pictures, description, reviews etc)
2. use different domain names (no problem if you use the same IP or IP-C address)
3. have a different layout (this is basically the key)
4. use schema.org tricking, meaning show (the very same) reviews on different scale, show a little bit less reviews on one site than on an another

Quick example: http://bit.ly/18rKd2Q
#2: budapesthotelstart.com/budapest-hotels/hotel-erkel/szalloda-attekintes.hu.html (217.113.62.21), 328 reviews, 8.6 / 10
#6: szallasvadasz.hu/hotel-erkel/ (217.113.62.201), 323 reviews, 4.29 / 5
#7: xn--szlls-gyula-l7ac.hu/szallodak/erkel-hotel/ (217.113.62.201), no reviews shown

It turns out that this tactic even without the 4th step can be quite beneficial to rank with several domains.

Here is a little investigation I've done (not really extensive, took around 1 and a half hour, but quite shocking nonetheless):

Kaspar Szymanski from Google Webspam team said that they have looked into it, and will do something, but honestly I don't know whether I could believe it or not.

What do you suggest?

• should I leave it, and try to copy this tactic to rank with the very same content multiple times?
• should I deliberately cheat with markups?
• should I play nice and hope that these guys sooner or later will be dealt with? (honestly can't see this one working out)
• should I write a case study for this, so maybe if the tactics get bigger attention, then google will deal with it?

Does anybody could push this towards Matt Cutts, or anybody else who is responsible for these things?

I guess you already know what the right answer is. play nice and hope that these guys sooner or later will be dealt with.
