We have a classified ad website.
Some fraudsters, scammers and kids crawl the content.
Some can be:
- aggressive, running several EC2 with multi-threaded curl requests resulting in 100'000s requests per hour.
- unfair, they will use the content for their website.
- dangerous, they will use the content to spam (email or SMS) the users.
- very dangerous, they will try to scam the users.
To protect our users against them, we would to do some cloaking (only with these limited and unwanted crawlers): modify the phone number, scramble the text, etc.
Is Google tolerant with this kind of cloaking?
