Hey gene,
Firefox doesn't permanently block the site, it justs put up a message warning you about the site and asking you if you wanted to proceed. That's what happened to my friend and he was shocked also being a member on the site. I use internet explorer so I have no firsthand experience of such an event, but I am surprised to hear about it.
I just searched for the harptabs.com on google:
[
www.google.com]
Under the link is a message saying the site may harm your computer. Clicking on the link brings up a page saying enter at your own risk. Whatever's going on, it looks like it's getting serious.
