The top two answers to this question were deleted:
The accepted answer's account has 19 of 20 answers deleted, all for promoting the same product, his product from his company. This user was subsequently suspended. While I don't disagree with this suspension based on the data, I think in the above specific question those answers are correct:
they answer the question
they disclose affiliation with the product
I have thus undeleted those particular answers only.
My beef with self-promotional folks isn't the promotion itself -- this is covered by the faq -- but that all they seem to do on Server Fault is promote their stuff.
If they had a more balanced mixture of genuine participation, and some REASONABLE, ON-TOPIC, DISCLOSED promotion, then I would not be opposed to it.
I have unsuspended the user in question because he has a number of valid questions at least and I strongly encouraged him to answer this post on meta.
Is there some way we can better educate folks about this before suspending them?
