is it not ok to post a link?

[Davidn]

I posted a link on a forum thread that had other links on the same topic, and received a ban as a result..
I signed up again as I do want to be a contributing member of this forum; can anyone clarify these linking rules?
Maybe I'll just be safe about it and never post a link again

I'm guessing the link was to a product being sold? Or something similar?

Hi David,

Could you send me a PM to "Moderators" with the details please? It's likely that a member with a single post that simply points to another site might have been identified as spam.
