today I noticed that may many years old free wordpress blog with hundreds of quality articles has been deleted
I had quiet many high SERPS in top 10 or top 20 even without any SEO at all except default SEO = a dozen high quality social bookmarks, 1-2 reblogs a link on one of my FB pages plus a submit to all RSS directories = hence each post got an instant 50-100 or so BLs for past many years already, most of the RSS directories = instant BL)
all changes I made in past 3-4 weeks is to build A VERY FEW links as part of random links to certain pages or the blog main page itself
few = over the past weeks max a few hundred links
links from quality human readable articles only
may be similar could happen to others using SER to link own blog to promote own site ?
