How to get all comments Vkontakte?

I'm doing that delete all your comments from the contact. The problem is that I can't get a list of all posts that I left comments. Use a method newsfeed.getComments and set the parameter start_time approximately 2003, the contact I was given a few dozen posts, I sequentially went through them and deleted their comments. The problem is that the parameter next_from empty, accordingly, the next page of data I can not receive. Why might that be?
My query looks like this:

1. Because there are no more comments.
2. Because VC has hidden limits some API methods.

It's a pretty sore subject due to the following problems:

1. Old records are very often difficult to load because of the lag VC. Was the real situation when the comments 2009 got only ten times(maybe more). It looked like a stubborn slotting in the API and wait for the response.
2. Try playing with the API versions(this is the first problem).
3. As rightly pointed out at the VC has a hidden restriction on methods. Please try again later.
4. Again attilas to the first problem - try with the web version and already there hands. Sometimes it works better than API, sometimes worse.
5. VC appeared in 2006, if I'm not mistaken, it is not necessary to put the year 2003, because this also can be a problem.
API is now more or less stabilised and is almost impossible to come across problems from point 1. - gunnar.Barrows commented on July 9th 19 at 13:49
: still meet. Worst of all, right now the bug works for siliconix records that summer. He crooked program and pays through the API. - karina59 commented on July 9th 19 at 13:52
In a web version on the comments page displays exactly what is given to my program via the API. But there can be so that no more comments. I often wrote them, they definitely should be. Try to put the year 2007 and try later. Thank you. I will write the results. - lori_Hoeger commented on July 9th 19 at 13:55
: can you appeal in support of the Ala: "I remember I wrote a comment in one cool group of the year in 2007, but now can't find, will you help?"
I once threw the entire list of groups where I'm admin, because some went out the address but could not find. - karina59 commented on July 9th 19 at 13:58
Support Vkontakte said "Comments only available for the last 20 days." Year I tried to put 2007, it wouldn't work. Now after a few days all the same. That is, it's not a lock, some hidden. - lori_Hoeger commented on July 9th 19 at 14:01
: so this is the hidden lock. You can get only the comments for the last 20 days. By the way livak, Google his name - almost all the comments and posts Google already pulled. - karina59 commented on July 9th 19 at 14:04
