    Collect user id vk impossible. And the services that do this - use holes in the system. And in general, it is, in fact, a crime, because not only identifiers are collected, but also the user's information without his knowledge - Alexey Shimansky
  • @ Alexey Shimansky, judging by the script, it collects not all, from those who put it on the page, and judging by the API, vk gives the ID of everyone who put it. Although I could have made a mistake in the script. - Nikola Tesla
  • @NikolaTesla is not, you are not right .... it collects from everyone who is on the page ... more precisely, who at least once clicked to any area on the page ........ just the widget is not visible to the user ..... user does not know that at this time on the page something like that is. So, any such maneuvers are not intentional - Alexey Shimansky
  • @ Alexey Shimansky, I see that information is sent to the mail from the VK likes.getList API function, that is, those who put likes. That is, the script itself does not collect anything. But if he puts the likes on automatically, I was too lazy to understand :) - Nikola Tesla
  • @NikolaTesla Script and collects .... in general, take your word for it, that in fact what is described there is a fact of violation of the user. - Alexey Shimansky

You can not do either one or the other. Since this is the collection of information of users without their knowledge, it is a kind of crime. You can collect IDs only if the user enters your site using approx. There are no other options for this day.
