There are various ways to disrespect visitors to your site. For example, you could show your mobile internet user site contents that differ from those given to the search robot for indexation. Thus, the user can't find the information they expected to get based on the search results. In these cases users are often redirected to sites offering subscriptions to mobile providers' paid content or services.
Various methods are used to redirect users to these services, from automatic redirects to aggressive ads that inhibit content access or purposefully confuse the user. Furthermore, the fact that such subscriptions are for a fee is not always obvious, and the paid content itself often doesn't reflect the users search query or the content that the search robot indexed.
If you want to avoid similar problems on your site, we recommend that you completely refrain from using ad services that manipulate or trick users via such techniques.
After correcting any such violations on your site, click I've fixed everything in the Violations section in Yandex.Webmaster. This way the robot will know that you've made changes.
The I've fixed everything feature is available once per month for each individual site. Keep this in mind and only click it when you're absolutely sure that you've taken care of all the violations present on your site.
If several people have management rights to your site, a specific person should be delegated to re-send the site for checking at a particular time. None of the admins will be able to use the button again for a month.
Restrictions are usually lifted within a month after the violations have been addressed.
These type of deceptive tactics are implemented in different ways. You can check how your website behaves on mobile devices by simply loading it and clicking around the pages (don't forget to click through to your site from search results as well).
Usually these types of deceptive methods are carried out using affiliate programs and teaser networks. Make sure that the ad networks your site uses don't employ such tactics and are trustworthy in general.
