Previously the social network "Vkontakte" gave the opportunity to each member of the system to leave your opinion about another user anonymously on his page. But for unknown reasons, along with other transformations, this function has been removed from the website interface.
So, remember that any programs that promise then I have to open you access to anonymous questions through the social network created by cyber criminals with the aim to infect your PC and demand money to unlock.
After the "anonymous opinions" in "Vkontakte" was banned, there are many websites created just to ask anonymous questions. Of course, the question to ask only the person who registered on this site, which significantly limits the possibilities.
Find out what service was the person from whom you want to ask anonymously. The most popular among its category sites "'t Ask.ru" and ask.fm (not to be confused with ask.com). There are others, like "Answer.ru" vopros.ru but the audience is much smaller.
Go to the website. Basically, in order to ask questions registration is not required. If you have it still there or did you decide to join any service, before you ask an anonymous question, check the below tick in the "Ask question anonymously". Otherwise your identity will be "unclassified".
On the Internet there are many different sites and apps that are supposedly after registration or installation declassify the one who asked you an anonymous question. In fact, it is impossible, as the creators of such sites are not stupid and will not allow their business stopped working. Data about the "anonymous" are not stored in the system.
Ask clearly worded good question, to allow the user to give the desired response. Do not insult another person anonymously. Remember that the person who addressed the question, has the right to refuse to answer.
