Posting content (articles, K2 items) back to Facebook is something we're looking into. Now that 4.0 is out, and mostly gone smoothly, we're starting to look into scoping out 4.1 and 4.2. Pretty sure that posting back will be in one of those releases. If you have any example code or things you've got working, we'd love to hear about it!
Thanks for your patience in the matter, and thank you for contacting Gavick. We will do it their stripping of tags isn't fixed in the future, but it's always best for them to hear it from their users.
Finally, please consider leaving a rating and review on the Joomla Extension Directory for JFBConnect, or our support. It's certainly not required, but very appreciated!

Best of luck,
