Why not? I assume it's available via Google. A simple pointer to a publically available post is no issue.
So what happens when people quote you, and the stuff that you've included unattributed? It seems that you lay yourself open to problems by effectively plagiarising other people's offerings, and also you lay other people open to any problem arising from their quoting of your posts with unattributed content.
If you can't be bothered to post properly, and don't care what problems you cause others, I think it's time for you just stop posting.
