I had asked a question about how I made an article. The article was basically a short form of several hubs with links to each article. Sort of a mini hub for a group of related articles that could loosely be consider a training program. The question linked to that hub so people could see what I was talking about and poof it was gone for being overly promotional.
My first hub came off of my website and was too similar to the original post and it came down too with no explanation other than the word duplicate content.
Each time I was on the verge of packing up and doing my writing on Info Barrel.
If it happens again well 3 times is a charm!
