Same response as in the other thread where you posted the substantially the same as "above"..
That would be "pay to play"..some people got their start in their online businesses via beginning with a hobby site , and building on it ..
If they had to register as a business with whatever "authorities" are responsible for "businesses" ( with whatever financial outlay that involves* ) depending on where they are that can be expensive ( * in France until very recently it was illegal to trade, even on the "net" without "registration" with the "authorities" ..the cost of which was fixed at an entry level of around $8,000.00 per year..whether or not you made a single cent profit the repeating annual cost was the same at nearly $8,000.00 ) add in your Google registration..and you have a system where only the people in business already could afford to be in the serps..
The mom and pops could not compete ..because they would be absent ..and any innovation would disappear within 12 months..
The carpet bombing keyword and search spammers and scrapers are exactly those who would have no trouble at all paying ..think "ehow".."about" etc..
The problem with the influence of the adsense driven element is that once the initial site is up ..there is no control, and that G does not police scrapers and copyright infringers with sufficient rigor as their own cache would fall foul of any rules they could make ..DMCA is and was not their idea..and is about as effective as "can spam"..
In the eyes of those outside the USA ..it is not effective at all..nor is it effective if you are scraped by someone outside the USA..
90% of the crap in serps ( those of Google or Bing etc ) could be removed overnight if Google would police adsense correctly instead of passing it off to searchers and website owners to report scrapers and scam and infringers..
I won't be holding my breath..
But paid registration with search engine(s) is what we call in French ( doubtless the same term exists in many languages ) "climbing the ladder and then pulling it up after you"..we all got into Google's serps for free, some began their businesses based upon their success whilst holding a day job working for the man, or were in school etc..
Why should those who come after us have to pay to play when we did not ? ..
If you are losing a race, running with two legs, the way to win with pride isn't to suggest shooting some of the other runners in the foot...apart from the fact it would be ethically wrong ..many "innocents" would suffer..and poor folks couldn't play..
"Pay to play" or "need a permit to play", is closer to old style soviet ways of doing things than it is to free enterprise..
Bear in mind also ..Google does not only operate in the USA..would you ban non US sites from targeting the USA, or appearing in USA serps ?..or US sites from targeting or appearing in non USA serps..?
Your "view" is extremely narrow and USA focused..and "protectionist"..we don't all have USA tax ID etc..nor need it ..nor would I consider obliging a US citizen to have French tax ID to see his or her site in French serps..and not all countries have a BBB nor even an approximate equivalent to it..
It is webmasterworld here where we are posting..
Transparency from Google would be more useful to some..but IMO it isn't ever going to happen..
They are going the other way with the referral data stripping they began last year..and I suspect that some time this year we'll se all referral data striped and they'll go to https for all searches ..signed in or not..and it will be said to be done for the good for searchers "privacy"..
Thus they'll home to divert flack from, what is IMO, their appalling privacy stance..
But your "solution" is far far too USA centric ( there is a web and serps outside the USA :) and presupposes that
a)
If you’re a web spammer from a foreign country
And if you are a web spammer from the USA..spamming either the USA or foreign serps..and very very many are from the USA ..then what ?
b)
tying to apply with false credentials
The biggest spammers..ehow etc..have real credentials..so real credentials wouldn't stop the big guys at all ..pinterest are ripping of people's copyright materials via their users at a staggering rate ..with real USA business credentils ..as are "about" etc..
And again would you recognise for example my businesses credentials ( I am registered in more than one country and in multiple languages ) ? or how much other cost there is involved in us getting them ..not evryone can start off business life as easy as using a DBA..
Hurting the little guys that you don't know, by insisting that they get embroiled in your bureaucracy, and produce suitable paperwork for it..because you think that the big guy Google won't change ( but you'd like Google to be the "web police" and keep "the other guy out of your hair" and "out of or below you" in "your serps" is not giving everyone an even break..
You are asking for favoritism for established USA business webmasters , over those who have yet to establish themselves , or who are based elsewhere..
You and I, and all the others here reading and on the web, didn't have to produce business licences to be in commercial serps, or "pay to play" when we began on the web ..why should anyone else, anywhere else, now or in the future..
You can be "scraped" just as easily by a legit paper permit carrying US business, as by a foreign legit paper permit carrying business or a non paper carrying one inside or outside the USA..
