Are you using HLP for some kind of SEO? That's the only explanation I can think of that makes any kind of rational sense; the periodic obsession with specific topics, the not-quite-copypasted articles that hit keywords, the random nature of the topics vs HLP, despite your pissweak attempts to pretend they're related.
If you're doing that, stop immediately. If you're not, stop spamming. Also immediately. Consider this your official warning - from now on, I'm applying the reasonable man tests to your posts - if a reasonable man would conclude that they're spam, then they're spam. And the reasonable man is me. Don't push it.
