Have you used the roboclick service?

Question

Search Engine Optimization

Good afternoon!
They called from the roboclick company and offered to bring 10 search queries to the top 3 for 35 thousand.
Their system emulates a browser, types a search query in Yandex, and then sits on the site for a certain time. That is, there is an emulation of a person.
Interested in whether Yandex will ban for cheating pf?
And most importantly, the opinion of real users of this system with real sites is of interest.
Advertising and incomprehensible messages with arguments about possible problems and negatives regarding the service, etc. I will send it to spam (there are so many reviews on the network, you can’t tell if it’s cheating or not). Interested in the opinion of real users and specialists who use this or similar services.

Answer 1

Don’t even think about it!)
Either you will waste your money or, even worse, you will be banned for 9 months. If the service starts to rotate pf en masse, it does this through patterns that are simply calculated by Yandex.

Answer 2

There will be no bans, but damn PF is woven among the factors at the end, and it is easy to stuff itself if everything else is done correctly

Answer 3

Everything works with a bang! The third month of our cooperation is underway, some of the requests are in the top, the other part, according to the forecasts of their specialist, will soon be there. It would be nice if they were also engaged in optimization! No comments!
