90% of the article directories out there are crap and will accept the bad articles being spunned, but the high end hi-pr ones all have editors and authoring mechanisms and manual reviews in place to spot on a spun article and they will never be accepted at a high rate - some good days when an editor is bored might allow a few but most days it will get you ban too for posting crap.
best is to have it done right, article marketing is very effective if done right.
P.S.
I didn't know J. Leger's TBS is available as crack in here LOL I have always thought he was a VIP in here or something
