I created (using 5-6 proxy in different countryes ) about 30 gmail accounts and 30 blogs ( regarding one niche and each blog name another longtail keyword ) also I created ON THE SAME WP account 30 blogs ( the same niche) I found 10-20 articles, I spined their contents, maked their content uniquer, but not too human readable. I set up a custom php script to post at some random blog ( via EMAIL) one random article choosed from another 300 articles inside an folder. Every posted article was containing ONE link inside it to another blog.randomly choosed. EVERY THING WAS RANDOMLY The inner structure was: blogger blog was pointing thru random links to random WP blogs ( the link was thru keywords) and the WP blogs was pointing thru link to blogger blogs after about 60-80 articles posted ..randomly in 3-4-5 days all my WP blogs was banned..reason.."my content was spam and machine generated" and also some ( 10 blogger blogs was banned "possible term violation") i verified and I DO not have more than 2 articles posted on one day on one blog ( accidental thing , because I used a random php function). It is wrong to post max 4 articles in 2-3 days on ONE BLOG wp or blogger? It is too much? Or my content was not human readeble? I runned that script not more than 3-4 times /day ..one script run post at 6 diferent blogs 6 random articles each of them having one random link to another blog... What I was wrong????Why I was banned? The method ,? The content ? , the freqvency?
