How do you distribute proper content to Social Networking sites?

I'm fairly new to submitting content to social networking sites such as Digg, Newsvine, and Netscape. I have submitted several articles to around 6-8 of the top social networking sites to date.

Seemed to be going through smoothly until I went to submit a few more new articles to Netscape and Slashdot, in which I noticed that my account was banner or locked, which I have no problem with, but they left me with no reason or warning as to why I was banned.

A warning or at least a generic reason for being locked out would be nice, but I have read that Netscape is pretty strict on their policies and procedures. What type of material should I be submitting to these sites? Should I be submitting more "news story" type articles?

Has anyone else shared the same experience?

 

Your accounts might have been blocked since you were promoting your own stuff, and it was deemend as spam??

 

One tip, when submitting the same article to several social bookmarketing sites: make sure the descriptions are different w/ different titles (if possible). So Google doesn't see it as duplicate content.

 

And don't make it obvious that you wrote it. Try to submit stuff from other sites too

 

There's a lot you don't know until you get booted or "repremanded". Change the ad a little; that seemed to work for me on Craigslist.
