As you guys already know, the problem is not as fixed as I thought it was when I posted this thread. That magical hardware turned out to be not as magical as I was told it would be, although it does work reasonably well when it's installed. The problem is that the hackers are figuring out ways to circumvent it, so pretty much every day we have to take the thing back out, upgrade it, and then reinstall it. While it's out of the system, PGC is completely vulnerable and tends to be totally unresponsive. After the reinstallation, it works great for several hours until the hackers trick it again.
I don't know whether this cycle will close up, i.e. we only have to upgrade once per week or something. If it doesn't, and this business of the site being up and down, up and down, up and down continues, we are prepared to take drastic measures. You are all very correct in saying that the ads and pop-ups are supposed to pay for good hosting and technical support, and it's not right for us to make you deal with all that junk unless we can provide an excellent site in good working condition. Again, please be patient and know that we are working very hard on the issue. We are extremely concerned about losing readers and advertisers because of this, but there is no way in hell that I'm going to let PGC die to some hacker punk kid.
