How to get the top commentators of a VK group without a token?

Question

In contact with

There is a script for getting the top community commentators. First, the posts on the wall are taken (wall.get), then the comments themselves (wall.getComments) and sorted into the top.
The trouble is that there are a lot of requests, and the groups are large. Therefore, the union in execute still does not save. And these methods require the user's access_token. Here is the question - is it possible to somehow get a universal token that will not have time limits?

Answer 1

We talked with VK support on this topic, in this case they do not go to a meeting.
Their answer: Frames for everyone, no exceptions

Answer 2

No way, moreover, if there are a mountain of comments, more than 1000 pieces, you break the request into several, with an offset of a thousand.
I wrote a dynamic cover for VK to order, so that the volume of commentators in a day and people who like it. If there are really a lot of comments on the entry, and there are unmeasured entries, VK simply cuts off the connection with you and there is no way to cure it.
