i wrote the post before the one of aleksl was approved so sorry for repeating. My situation is similar to many others. My site had about 9900 BL one month ago, according to opensiteexplorer. It was slapped on the 27 April and i checked what the reason might be. Suddenly i saw around 53.000 BL on opensiteexplorer, so its clear that the competition or someone did some BL for my site, since there is no way i could get so many links in such a short period of time. My site deals with information about TV channels, such as own written description, contact information, official logo, satellite availability and link to the official stream (if available). There is NO LIVE stream on the pages, since its illegal without the copyright's owner agreement. There is actually NO WAY i could remove the remaining 40.000 BL even if i had 100 more years to live. Its my own experience how someone with bad intentions could ruin a website and the work of more than 4 years. I'm dealing with websites for the last 8 years and black seo is not my type as i know that at a certain time G will penalize it and I got only original content written by myself. ITs better to have less content but better quality. This mostly concerns keyword stuffing, doorways....etc, things i can control, but I'm totally out of control regarding the BL so G should be aware of this. I read the article you linked to but it doesn't help in removing links or convincing G to change the algo so that at least this links will be devaluated without penalizing the site.
