Most sites recently have been hit with a drop I have found. I doubt its just BMR. Many other article networks have been hit too.
That's possible (even likely, knowing the algo-focused brainiacs at Google) but as someone who is trying to find techniques to rank, I don't really care if BMR was targetted or if things like BMR (including BMR) were targetted; the fact is that BMR, IMO, is no longer effective as of mid-February.

I think its very dangerous for Google to start de-indexing sites that are LINKED to by blog networks as it opens up a whole new industry: Anti-SEO.
I don't think Google is de-indexing sites that are linked to by BMR. I think Google is devaluing the BMR sites because those sites fit a profile that Google has determined have little value-add. So those BMR sites may have had some decent PageRank pre-Feb but now Google has valued them at zero (or near zero) and so now they pass zero (or very little) PageRank to the sites they link to.
I have been using BMR for a year and here is what I noticed 2 weeks ago:
(1) Site is 6 years old. Added a sub-page 6 months ago and was BMR'ing it. No other link building was done for this page. Page was not spam-like (nor was the site). After 3 months the page ranked #10 for its keyword. After 5 months it ranked #5. After 6 months it ranked #3. Then, with no other changes to the site or page, it drops to #40 in mid-Feb. The only explaination, IMO, is that all those BMR links that were pointing to it lost their link juice. (And, yes, the anchor text backlink profile was natural looking, the page was not keyword stuffed, it loaded quickly, the content on the page was unique and interesting for humans, etc).
(2) A second (unrelated to (1)) domain is 10 years old but site is 2 years old. 200 pages of unique hand-crafted content that have been added at a rate of 1-3 pages per week for 2 years. BMR was one of several linking strategies to create deep links to all sub-pages. For many pages it was the only strategy. Rankings were increasing every week and i had over 100 phrases on page 1 organic results. Then, in mid-feb, overnight I lose 20 of the 100 page 1 rankings (still indexed but now at spots 20-40). The largest drop (and only significant drop) in the 2 years the site has been up. I looked up the pages that dropped and the only thing they had in common was lots of BMR backlinks. The site was fresh, many of the dropped pages were fresh (we tweak them a little every couple months), the backlink profiles were natural looking, the pages were not keyword stuffed. Basically, among all the variables, the only variable that could be an SEO red-flag are the BMR backlinks, IMO.
