Subscribe to vk.com users and groups
By default only wall owner posts are shown. Use foreign_posts=1 option (e.g. subscribe to vk.com/my_group?foreign_posts=1 ) to get them.
Discontinued vkontakte-feed feeds are handled automatically and should work again.
VK blocks content too. Although if you oppose USA and not Russia it surely won't be blocked ;)
As Twitter censors content as itf it's some Soviet media platform I decided to move to VK.
Looks like a VK bug. I'm making less that allowed 3 requests per second yet get these errors. Added additional delay to never make more that one request per second. Hope it will help.

Too many requests per second
Probably vkontakte-feed sources are better, vk-rss works only for users (not publics or anything else), and it does not work even for some users.
This seems to be really easy to implement. Getting json file with vk wall is as simple as http://api.vk.com/method/wall.get?owner_id=1&count=90, i.e. http://api.vk.com/method/wall.get?owner_id=1&count=90 for Durov's wall.
Here is the simple PHP script which parses this json and makes RSS of it: https://code.google.com/p/vk-rss/
For now I use my own instance of this script.
This service stopped working, no way to read vk.com with bazqux now.

There is a service for this - vkontakte-feed.appspot.com. I am using it to get feeds in BazQux.
