onlinesource - To note a disavow resource that was also mentioned in your other thread. I get the sense you didn't follow through, or you wouldn't be asking again about Russian backlinks again....
Up in the top of I believe just about every page on WebmasterWorld, in the upper left just next to our logo, is a
free tools link [
freetools.webmasterworld.com...]
The first tool listed is a backlink checker that I think will help...
Google Backlink Checker Tool for Penguin & Disavow Analysis http://backlinks.webmasterworld.com/google-backlink-tool-penguin-disavow/ [backlinks.webmasterworld.com]
I strongly recommend that, before you do anything, you view the two videos about using the tool on the above page. Full disclosure... these tools and the videos have been posted by Jim Boykin, whose company owns WebmasterWorld. The tool is in beta, and is free.
The videos are the most granular presentation I've seen about the kinds of patterns to look for in analyzing backlinks for disavow... but watching them does take time, focus, and attention. I recommend watching them a second time if you don't get it the first time.
As the videos suggest, there's no pushbutton way to approach this. The patterns can vary from site to site. You will note that .ru backlinks are one of the things Jim mentions in the videos, and yes... unless you're selling vodka or caviar... I'd get rid of them.
Somethat that might help in your situation would be to look at your backlinks sorted by date... as that would help isolate links that the SEO company you'd hired might have acquired for you. That said, the timeline for those links might not be precise, so that alone won't solve your problem. Take a look at this article by Barry Schwartz...

This may be one of the more useful feature upgrades to the link reporting tool within webmaster tools. Being able to quickly see your most recently acquired new links might be helpful in tracking link acquisitions, as well as determining which links might have caused a penalty.
