As one of the mods here I generally perform a web search on the first paragraph of any post that looks meaningless or is not remotely related to what this forum is about -- if I find that paragraph verbatim on other pages I assume it is some sort of SOA poisoning of keyword playing and I delete it as spam.
However, if there is the tiniest possibility that it is a genuine post I tend to leave them.
Posts containing a direct link to another site/product without any sign of personal 'talking' I generally regard as link spam. If it's someone's first post, I assume it was a drive-by link spam.
I don't remember deleting any posts from you, but then I can barely remember what day of the week it is. Sorry if it was me, glad you stuck around so we know who you are.
I've always thought it a good idea when you're new on a forum is to lurk for a bit and then post on existing threads, or start a thread introducing yourself, before leaping in to create new threads with external links, otherwise there is a tendency for regulars to think 'who is this guy and what does he want from us?'.
Welcome to the Coffeehouse, it's an interesting place to talk once the natives have accepted you as one of their own.
