Why are my posts flagged as inappropriate/abusive and deleted?

I take my own time and effort to help folks on these forums, yet my posts are always flagged as 'inappropriate/abusive' and 'need to be checked by a moderator'.  I got an appeals email which I didn't see so missed a deadline to appeal, so my post is just deleted.

If any one of the moderators is reading this, the relevant url is below.

I am never told quite what is 'inappropriate' or 'abusive' in my posts.  I have had this issue numerous times, but this time I missed the appeal deadline and so what I posted, or tried to, was basically a complete waste of my time.

Frustrated.
